[Screaming .357G]

Just thought it would be a good idea to get a sticky started on some .357 sig loading data.

I see a little info here and there on the .357 sig and thought it would be a good idea to just have a spot for it.

Maby a collection of web pages like petes or something we could make a list to help out the people wanting to start reloading the .357 sig.

Stuff like what primers,powders,brand/weight bullets etc.
Even include some stuff on what guns they loads/barrels were tested etc.

Here is just a small example of some form of data that may be helpfull if we just put it in with a buch of other pages,ideas,etc like it.

Just a note: The Sig Forum is interesting; it was the home of the first .357 Sig guns.
Enjoy.

Here is a most interesting thread on various reloading issues.

If you are new to reloading use caution; some of the information or techniques may not be for beginners.

I spoke with an Alliant Tec Rep about Power Pistol:

1. He doesn't like the flash either.

2. PP is derived from the Bullseye formulae, it meters well because of its shape, but there are some ignition issues that are exagerated by slowing down the burn rate. He recommends the longest barrel practicable to get a complete burn every time (lower standard deviation numbers).

3. He uses PP in his 357Sig, so he had noted the same problems/complaints that have been expressed elseware in this thread.

For accuracy from 80% max to max loads, power, low flash, low smoke and easy metering: I am enjoying Hodgdon Longshot increasingly in my reloads!

Accurate arms has lots of data. I have had great results with #7

I hope you will allow me to sneak in here with an unusual reloading problem.

I've been reloading this caliber for about 4 years. For the past couple of years, I've been using 12.5 - 13.0 grains of AA#9.

I enjoy great performance for the first few dozen rounds and then failures to go into battery problems begin and get progressively worse. I have eight .357SIG handguns, some have stock barrels, some use Bar-Sto barrels, some use KKM barrels and two Federal Arms barrels and this problem occurs in them all. If I scrub the chamber with a dry bore brush, the problem goes away, but will return if I continue shooting.

I've tried many varieties of quality bullets, both plated and copper jacketed and there is no difference. I've come to the conclusion that it must be powder residue buildup...I just don't know why. I've NEVER heard of anyone else complain about this problem.

Any ideas/comments?

[jcmios]

#9 may be leaving un burnt powder or excessive powder residue. Try #7 or any other pistol powder but not shotgun powder as it leaves too much residue also. You could try magnum primmers, but will possibly need to lower the charge weight.
The Accurate Number Two manual shows 11.7grs to 13.0grs for a 124 grs Gold Dot bullet, try cutting your charge to 11.7grs and see if that helps.

I was wondering if my crimp was insufficient. While it seems to hold the bullet in place and I don't see evidence of setback, I try not to be too heavy-handed with the crimp so as not to distort the case shoulder.

RCBS dies have a roll crimp and a 2 die set.I was using them but I just picked a Redding 3 die set with a taper crimp and I going to find out how they compare.

I've only dabbled a little with AA#7 with respect to Accurate Arms in this caliber. Maybe it is some unburnt powder. Do you crimp enough? Do you use magnum primers? Most powders burn most efficiently at near max or max pressure for a given caliber.

I use the lowly and humble Alliant Unique for my 357 Sig reloads. Using 124 gr plated bullets and 8.0 grains of powder, my chrono recorded an average of 1402 FPS at a ten feet distance. I'm sure this is not a max load either. No unburnt powder (flakes spattered on my arms) and the cases do appear clean internally.

A very wise fellow reloader on another gun-related board knew exactly what the problem was and it has now been fixed. I needed to bump the case shoulder back a little further with my sizing die... about .002" or so. I had two possible options to accomplish this. I could either remove some steel from the bottom of the die or remove some steel from the top of the shellholder. I chose the latter option. All of my .357SIG reloads perform perfectly now.

The tolerence of my sizing die didn't allow for the accumulation of any unburned powder residue.

[Washington,D.C.]

That's interesting to know.I just switched from RCBS dies to Redding dies and they came with rifle die instructions rather than tapered crimp pistol die instructions.I always worry about pushing the shoulder back too far.With straight wall pistol cases I set the die to touch the shellplate.With rifle dies I leave the proper gap.So it looks like with at least some 357 Sig dies they are making them to use like other pistol dies.Catbird,what dies are you using?

[Catbird]

My .357SIG dies are RCBS. I followed the printed instructions and adjusted the sizing die down till it touched the shellholder and then turned it 1/2 turn further. This obviously didn't allow my cases to go far enough into the die. Thinning the shellholder a tad cured the problem instantly.

(The shellholder was NOT out of spec. before I modified it.)

This problem had previously caused me quite a bit of frustration as I experimented first with THIS and then THAT to no avail.

I came very close to calling it quits and ordering a set of Dillon dies...glad I didn't have to.

Thanks for the info Catbird.Redding use to make 357 Sig Dies with a roll crimp and a taper crimp die was an option.Now they supply a taper crimp die with the set.Maybe I'll get a Redding shell holder to match it.I want to compare the bullet holding of both dies on 9mm bullets.Redding even makes taper crimp dies for 38/357 and 44.That might interesting for loading 9mm bullets in 38 Special/357 magnum cases.BuffaloBo my Speer manual list 8.0 grains of Unique as a max load with their 125 grain bullets.their starting load is 7.2 grains for 1231 fps and a max of 8.0 grains for 1344 fps.Alliant list 7.5 grains of Unique as max load for 1300 fps.
