357 SIG

Dennis, what LongShot loads have you worked with and what velocities did you achive if you measured them?

Hi Shadow,
Sellier&Bellot 2x fired cases
Speer TMJ for 357Sig..............Longshot at 9.3grs individually weighed
Ave for 20 shots= 1419fps measured with a old Chrony 1 at 10' from muzzle. The chrony may not be the best but its all I currently have available.
Recoil was acceptable and control was good.
The S&B brass has the tightest primer pockets I've ever encountered and seems to require more force to resize than my Starline brass does. But it is holding up so far. I still have to test the Noslers and the XTP's.
Ooopps; the gun is a stock barreled G31.

Dennis, thanks for the lad data, they correlate well with the Hodgdon data.  I hear you about the S&B brass primer pockets, they are tight feeling because the use a crimped in primer system.  I found this out doing some 38spl cases some time back, its a PIA, but a quick pass with the deburing tool makes them easier to seat the primers without crushing the primers.

My SIG P229 has both factory 357 SIG and .40 S&W barrels. Both calibers use the same springs, slide, and magazines. I can probably do the barrel swap in 30 second or less.
