357 SIG reloading problems

roysha

In a previous post, some mention was made of a problem reloading the 357 SIG. Specifically, what is the problem? I have loaded many, many rounds of the cartridge and I guess I was too dumb to realize I was suppose to have a problem. By the way, next to the 45 ACP, this is in my opinion, the best semi auto handgun cartridge around. Actually prefer my revolvers, don't have to * brass, but for a semi auto my SIG 226 in 357 SIG is VERY hard to beat.

I to am a big fan of the .357sig I have a Glock31, A Sig pro SP2340 in .357 sig and also a P229 .357 sig. The only problems I ever had reloading it was with Corbon brass,it seems to me it is very delicate and is bad for spliting at the tip of the hull.I have taken extra measures to be careful with it with the same results.Triton ammo is the same way,of course it also is made by corbon. The last lot of loaded corrbon I bought,a 500rd case was all loaded with Winchester caseings. Naturaly I shot about 100rds, and reloaded them without any problem.

Hope this helps.

Speer gold dot brass has worked well for me.

A great rifle with a junk scope,....is junk.

Reloading 357SIG requires a few points to be kept in mind for safety and success. Though the projectile diameter is the same as for 9mm, selection of bullets is limited mostly by the profile allowing sufficient flat for proper taper crimp (if you choose to do that step - read below) once the bullet is seated to the proper overall length. Because of the very short neck, resizing & trim-to-length have more of an effect on OAL and bullet neck tension than with straightwall cartridges. Also, there's some debate on whether 357SIG headspaces on the shoulder or on the extractor so resizing brass can be adversly affected depending upon choice of dies and your particular weapon. Load data should be carefully folllowed for bullet profile, weight, and brand - again because of the differences in profiles between 9mm and 357SIG-specific bullets.

Look for a post about "Achilles Heel" perhaps halfway down the first page.

Found this after awhile - might be basically the same information.
