Your Experience:

If you have tested bullets that either "work well" or "not" for the 357 Sig and would like to share your information, I'd be glad to add it here with your recommendation. I can't add my name unless I actually test it myself.

For quite awhile, I have believed the bullet diameter range for the .357 SIG to be .355 to .356. You can get a 9mm .355 bullet to work in a 357 SIG case if it is shaped correctly and the correct bullet crimp is used for the type of bullet being used. After doing my own limited testing, I now believe the 357 SIG ideally should use a bullet diameter between .3555 to .356, and not the standard size .355 bullet, if possible. The correct bullet size and shape is a critical step to minimizing bullet setback. A main reason West Coast Bullets and Rainier Bullets work excellently in the 357 SIG caliber is because they happen to measure .3555. The SAAMI maximum for the 357 SIG bullet diameter is .3555.
