Steel Shot Reloading Primer

 

[As posted on Duck Hunting Chat]

3200 man, I did my best to keep the word salad to a minimum.  But be forewarned, I’ll likely add more verbal clutter to it as I update it. 

I didn’t have a mentor when I started—and I’m not sure if that has been a good thing or not.  If I had had a guide, I’d have avoided a lot of dead ends, waste, and missed opportunities; then again, stumbling along has led me into some interesting side channels and eddies.  I’d love to give advice to anyone foolish enough to listen, but out of fear of ruining a possible spirit-journey of self-discovery, I’ll restrain myself to a few observations. 

First, not all gauges are as easy to handload for as the others.  Obviously, since the 12 ga is the most popular gauge, it has the most support in terms of components and data.  The 20 would probably be the next best supported.  The 16 and 10 gauges require more persistence and creativity.  The 12, and even more so the 10, are also easy because there’s enough room in the hull to make “normal” duck and goose loads. 

The following is a quick rundown of what you need to know to handload. 

I.                         Data 

The most important consideration is your data source.  All data sources can be divided into three parts: published loads, internet hive-mind, and self-produced.  First, there are several companies that publish handloading guides and they don’t always agree.  Some are more stick-in-the-mud, some are more innovative, but they all have something worth reading.  The trouble is figuring out what that something is…  The prudent thing is to collect as many sources as possible and triangulate the good data.  I would start out with Lyman’s manual.  It’s fairly conservative, but trustworthy; if you stopped there, you wouldn’t be far wrong.  I’d also recommend supplementing Lyman’s with manuals from Reloading Specialties (RSI), Precision Reloading (PRI), and Alliant Powder.  Ballistic Products (BPI) publishes a lot of books, but upon not-too-close scrutiny, a lot of their data doesn’t make sense: too many components to fit in the hull, velocity and pressure values dropping off with increases in powder or being wildly different from other data sources, or just weird combinations (12 ga 3.5” hull with 1.125 oz of shot?).  They have some good loads, but it’s not the place for the beginner. 

The second route of information gathering is off internet forums, YouTube, and other social media.  Here there is a lot of good data—and a ton of bad.  Sifting the diamonds out of the coal tailings can make a BPI book look like the First Epistle to the Thessalonians, but it can be worth it.  The trick is to be conversant in the published data already.  That way, you can see the red flags before you go too far down Bubbas’s shotshell log ride.  There are a lot of guys who have a lot of knowledge and experience—just know that they are dying off, so get on the question-and-answer time while you can. 

Load data can be developed yourself—meaning, you can dream up a wildcat load and send it off to be tested at a proof house.  This is somewhat expensive and time consuming.  If you chose this path, you still at least need the other data sources for a starting point.  So just go ahead and buy the books and read them.  

II.                      Tools

There are many ways to skin a cat, some more minimalistic (just use your teeth), some less so (operating room).  I once saw a prepper load a shot shell with a screwdriver and a candle, but I’d recommend a little more equipment as a minimum. 

·        A good grains scale.  Get a good one—not some nameless Chi-Com rip-off.  A lot of smokeless powders don’t take up a lot of room but build pressure quickly.  A double charge of powder can have negative results; conversely, a half charge of powder could end in a wad stuck in the barrel, which can have even more negative results.  You must be able to confirm you powder drops. 

·        Press.  The MEC 600 Jr is the F-150 of presses, but there are others.  And some old presses from the 50’s and 60’s can be retrofitted to work with plastic shotshells.  They’ve gotten pricy now, but used ones can still be found cheap(er).  If you’re intending to load non-tox, I’d stick with the single stage press.

·        Shot and powder dippers (I use a teaspoon).

·        Utility knife or shears for splitting wads and trimming hulls.

·        Sharpie for marking shells and boxes. 

Alternatively, some folks forgo the press and buy a roll crimper.  The advantage is a lower capitol investment (assuming you already have a hand drill or drill press), since a high-end roll crimper costs $50-$60 whereas the cheapest press costs about $75 (new).  The disadvantage is a lack of versatility, and more importantly, the requirement to only use new hulls.  (I know, this isn’t strictly true.  You can deprime and reprime with a punch, a mallet, and a block with a hole in it.  And for resizing, a MEC Supersizer resizes shotshells and isn’t a press, but it costs as much as a press.  Or you can get shotshell resizing dies for your metallic press… which is a press.  Or you can buy a resizing ring for the Lee Load All II and force it down over the brass and then off again, but this requires some leverage from some kind of tool—some kind of “press”.  Conversely, if you can find an old Lee Load All kit or one of its Ukrainian rip-offs, you can resize with hand tools.)  

You’ll end up with a raft of small hand tools for preforming small tasks.  Magnets for catching primers, plumb bobs for flaring case mouths, scraps of wood and metal as spacers, punches for poking things… This is where the true individualism of the handloader shines.  

I.                         Components

Hulls.   The body, the case, the SHELL of the shotshell, is nothing more than a plastic tube closed at one end with a paper or plastic plug.  That said, it is of utmost importance to know what kind of hull you’re using.  At the very least, it helps make you look like you know what you are doing, but it also will allow you anticipate problems with the fit of components.  There are many different brands, but they all fall into two main groups:  

Tapered.  These are mostly from target loads like Remington STS (same hull as Nitro 27, Gun Club, Game Load and Federal High Over All) and Winchester AA-HS (High Strength) or the old style AA-CF (Compression Formed).  These are generally best suited for target loads or some lead and bismuth field loads.  I wouldn’t recommend these for steel shot.  (There are some lighter steel loads for them, but the great advantage these hulls have for target loads, viz. reduced volume, is a decided disadvantage for steel shot.)  Do NOT use data for a straight-walled hull in a tapered hull.  First, it likely won’t fit very well, but if you do get it to fit, you can create some super high pressure. 

 Straight.  Federal Gold Medal and Top Gun (new), Fiocchi, Cheddite, and Rio.  I’d also include Federal .090” base one-piece and Hi-Power paper basewasd hulls in this group; Federal has discontinued both the .090” base one-piece and the fiber basewad hulls in the recent past, but they’re still bouncing around.  These are all straight walled hulls with flat-ish plastic basewads.  These vary slightly in volume, but for all intents and purposes, load about the same.  Any stack height issues can be solved with a bit of felt or some such filler.  These are the most versatile hulls.  The main difference you’ll encounter with straight-walled hulls is the primer pocket diameter; the European primers tend to be a few thousandths larger than American primers.  So a Win. 209 will be loose in a Rio hull.  There are tools and techniques for tightening up the pocket if you feel the need to use eurotrash hulls.  Myself, I simply avoid Rio and Fiocchi hulls for the most part.      

It’s important to know that the name printed on the hull doesn’t necessarily mean anything.  Winchester has used Cheddite hulls, and Federal has used Rio’s, to name two examples.  And even within a company’s line up, names get thrown around onto whatever hull is in the way.  For example, Remington’s “Nitro Steel” uses a straight-walled hull with a .20” yellow or a .25” black plastic basewad; “Nitro 27” target loads use STS style hulls; and “Nitro Pheasant” heavy field loads either use an STS-style OR a straight-walled hull with a .20” yellow plastic basewad.  Always check the inside of the hull! 

It is also important to know that the length of a hull is nominal; manufacturers may cut them shorter to better fit their loading process.  In fact, for the most part, the 3.5”, 3”, and 2.75” hulls from a particular brand have the same basewad profile.

My suggestion would be to standardize on one hull brand.  This is, of course, something I have never done—and I probably never will.  But the simplicity of the idea seems wise.  My second suggestion is to take one of every new brand and type of hull you encounter and cut it in half lengthwise.  Keep these cross-sections for reference.  This is something I DO do and have found it to be very informative. 

Primers.  You will hear guys refer to primers as either “hot” or “mild” or some such.  What they’re trying to describe is the brisance, or the shattering capacity of the explosive compound in the primer.  The “hotter” primers ignite more of the powder at once, and generally produce more chamber pressure.  This can be desirable under certain circumstances, say in cold weather or with harder to ignite powder.  Generally, it’s assumed that replacing a “hotter” primer with a “milder” one will lower PSI.  But you know what they say about assumptions…  This is a generally accepted ranking of the commonly available primers from hot to cold, but I have seen some place-switching on other lists.  

·       Fed 209A
Rio G-1000?
CCI 209M
Ched CX2000
Win 209
Fio 616?
CCi 209
Rem 209P

But there are also the Nobel Sport 688, Cheddite CX1000 and CX50, Fiocchi 617, and Wolf 209 primers that fit in somewhere.  And then there are old primers that still turn up like Alcan 220 MaxFire, Federal 209, Remington 57* and 97, CCI 197 and 109, and Winchester-Western 209 in the white box (which some claim are different from the current form).  Aaaaa….

AND, sometimes the “hotter” primer produces a lower PSI in a given load.  You can’t really count on primer heat rankings. 

If you’re loading targets, it’s not such a big deal because there is data for just about every primer.  If you’re using Win AA’s, WAA12, and Red Dot, you’ll be able to use any primer with a simple adjustment to the powder drop a grain or two.  If you’re loading hunting loads, especially steel, you’ll want mid to hot primers--Fed 209A, CCI 209M, Ched CX2000, or Win 209—since slower powders often require hotter primers to insure proper ignition.

Powder.  There are something like a million different powders, and about half have some use in shotshells.  But to simplify, you have fast, medium and slow powders.  Their use is relative to gauge, i.e. slow powders work for small bore target loads but large bore magnums.  You will find some data for almost all powders, but a few carry the brunt of the workload.  Stick with those powders if possible.  Unfortunately, periodically, global politics conspire to suck up the powder supply into artillery shells, and we handloaders have to make do with what we can get our hands on. 

For the best steel loads, Alliant Steel powder is king across all gauges, but it is hard to come by now.  There are several other powders that work, but some are hard to get, discontinued, or have limited data.  If you see these powders, buy them:

·        Alliant Steel.
·        Blue Dot—hard to find, lots of data, but not as versatile as Steel
·        Lil’Gun—not as efficient, limited data for 12 ga, but readily available.  Great 20 ga powder. 
·        3n38—available, some promising data, pricy compared to Hodgdon powders.
·        Longshot—available, can make lighter steel loads.
·        3n37—also has some lighter steel data
·        HS-6—available, can make light steel loads
·        BPI is selling some Vectan powders to fill the steel niche: STL, STXL, and ST2XL.  Data is only just coming out for them.

There are some discontinued powders that worked for steel to one extent or another, which you should buy if you run across them: 800x, 4756, N105, Solo 1500, HS-7/571, and possibly others.

Some other powders can be made to work depending on your expectations.

Wads.  Some wads are meant for lead (and can be used for bismuth), and others are meant for steel and tungsten shot.  Don’t use steel shot in lead wads.  The tricky part is the naming; there is no industry convention, and every manufacture or distributer is intent on using seemingly random collections of letters and numbers for their nomenclature.  This is compounded by the American importers of European wads, namely BPI and PRI.  For example, the Italian company, Baschieri & Pellagri, makes a 12 gauge wad for 1.125 oz of steel shot called simply “STEEL 32 Cal 12 H.7”.  BPI sells it as the “CSD118” and PRI as the “TUWSBL32”.  Just rolls off the tongue, don’t it?  It probably has other names too.  The only way around this is to read the literature carefully.  

Each handloader seems to end up favoring one or two designs (myself, I tend to find the B&P wads the easiest to work with).  But there are decent loads for all of them.  The unfortunate thing is, despite the suppliers’ marketing blurbs, there’s no way to know which wad will work best in your shotgun and choke without trying them out.  You WILL end up with partial bags of various wads, so just be OK with that. 

Shot.  There’s not a lot to say here.  I haven’t noticed a difference between the various suppliers in terms of quality or performance.  The plated stuff is nice and shiny, but I don’t know that it matters to the duck.  I say get it where it’s cheapest.   

Fillers and Buffer.  In order to get a good crimp, you need to have the hull filled up to a certain point, however, some loads don’t take up enough space.  In that case, we use fillers made of bits of felt, cork, cardboard, seeds, cheerios, plastic beads, foam—basicly anything light weight and fairly smashable.  These fillers can be placed in different places in the hull for different effects: a gas seal or a nitro card between the wad and powder will raise the wad and shot up in the hull and may provide a better seal to keep powder gas from escaping; this can increase FPS and PSI.  A disc of felt or cork inside the wad under the shot can raise the level of the shot and add more cushion to the wad collum; this can lower PSI.  A felt, cork, or card on top of the shot can provide a nice flat base for the crimp (especially helpful with large shot); I don’t know that this has any impact on PSI, but some claim it can disrupt patterns. Loose beads or seeds can be added under or on top of the shot as spacers, but don’t have a meaningful impact on FPS, PSI, or pattern (as far as I know).  

Buffer is a fine grained powder used to fill in the spaces between the shot in the hopes of improving patterns.  This is generally only used in lead and bismuth hunting loads, though some data calls for it with steel and tungsten.  It will raise pressure in a shotshell significantly.  Some people swear that it improves patterns, but I am more than skeptical.  Just know that if the data calls for buffer, you can always safely delete it.  But do not add buffer to a non-buffered load. 

III.                   Process:

This is the straightforward part. 

1.        Resize the brass

2.        Deprime (this usually happens at the same time as resizing)

3.        Reprime.  Make sure the primer sits flush in the hull.

4.        Add powder charge.  Be sure of the weight.

5.        Insert wad.  There is disagreement about how important wad pressure is.  It isn’t.

6.        Add shot charge.  Again, make sure of the weight. 

7.        Crimp.  It needs to be tight and flat (a slight dish is ok) with a slight inward taper, but not too deep.  A lot of guys are concerned about a swirl in the crimp, but this is more of a cosmetic issue.  Of far more importance is the depth—to shallow can lead to lack luster performance, too deep can cause excessive pressure.

Just follow the instructions that came with the press.  If that doesn’t make sense, the interweb is full of tutorials on how to troubleshoot your particular machine.  Most presses are designed with lead target loads in mind, but if you’re loading non-toxic shot, a lot of the steps will happen off the press.  The large sizes of steel shot used for hunting and several of the powders used for them don’t meter very well through a charge bar and require hand weighing.  This usually isn’t a problem given the lower volume of hunting loads needed by most of us and the long off-season in which to load them. 

The best policy is to establish a rhythm to your loading and don’t rush.  You might use the stage method, in which you resize/de-prime all your hulls, then prime all of them, etc.  Or you might decide to send shells through the whole process start to finish one at a time.  The important thing is to do the same thing every time to avoid mistakes.  Part of your rhythm should be periodic quality checks: check the powder and shot charges, crimp depths, primer seating.  I’d say, start by checking the first ten shells, then another one or two every box.  Depending on your set up, you may have some drift in the weights as the powder and shot levels drop in the bottle.  Just pay attention. 

IV.                   Suggested Loads?

Unfortunately, this all depends on what powder you have available. 

If you’re lucky enough to have Alliant Steel, The standard 12 ga 2.75” load, what most call the HG ( I prefer “The Iron Fist”), is:

12 ga 2.75” Cheddite
Cx2000
34 g Steel
CSD118
492 g #2 steel (you may have to remove a few pellets to make it fit)
~1450 fps @ <11,500 psi

The 3” version is similar:

12 ga 3” Cheddite
Cx2000
35 g Steel
B&P wad
1.25 oz steel shot
~1425 @ <11,500 psi.

You’ll note I’m soft on the fps and psi.  The reason is not some sort of blasé attitude toward safety.  Rather, I’m trying to draw attention to the un-uniformity of shotshell handloading.  I can follow a recipe from a reputable data source to the letter and still end up with different results.  The reason is lot to lot variation in componants, as well as variation in process especially crimp depth/tightness. 

If you’re looking to use powders other then Alliant Steel, I’d prowl about the various forums and make friends.  There’s actually quite a lot of info out there.
