Hello all. This is my first post here. I have greatly enjoyed reading other people's comments.
So I just started reloading .357 SIG and have a slight problem. I'm using power pistol with a 124 gr HP. Every manual/online resource I've seen puts the starting powder for this load around 7gr. I started this at 6.9 just because I'm new to the round. After cranking out several on my Dillon, I took it to the range.
Shooting through my buddy's chronograph, the round was zipping off at around 1600 FPS! The loading manuals have this load at 1200 so we were concerned.
We shoot my Glock 22 and the .40 came in right were it was supposed to (around 1000 - 1200 based on the round). We even tried the AR and got about 2800. So I don't think that it was the Chronograph.
I've checked and rechecked my powder throw and it's dead on. I know that extra powder is not getting in there.
Any suggestions on things I could check out? Anyone have any experience with power pistol in the .357SIG?
THANKS!
