.357 SIG powder and bullets recommendations

Any time. Good luck, and enjoy! The SIG is fun to shoot. Keep in mind, you may want to go with a slightly heavier recoil spring if you use full power loads. The XDm comes with an 18# spring from the factory which works well with factory loads and light plinking loads. But with full power .40 and .357 SIG loads, I ended up going up to a 20# and it smoothed it out a good bit. I have a 22# I will be trying soon to see if it makes it smoother or if it is too much.

I'm wondering how it will be for the Glock 32? This is what I'll be shooting.

Recoil springs are cheap, usually around $7-$8 a piece. If it is a Glock, most dealers carry springs for them, at least in my area. I'm not familiar with the Glock, but it should do just fine. If it was a .40 and the factory spring is still in great shape, you should be good to go. My factory spring was fine, but the heavier one smoothed out the snappiness of the full power loads that are running 1,480 fps - 1,500 fps.

Nice. You got them moving at 1400 plus. Awesome. I have a chrono as well.

The XTP & Gold Dots I push hard because I've been using them when checking hog traps to dispatch wild hogs as well as when I'm hunting if they come by close enough to pop them. So far they have done pretty good. I use Longshot to push them that fast. Power Pistol is slightly slower, but is more accurate... only about 30 fps slower on average. With the Xtreme, I have pushed them over 1,400 fps, but the accuracy was not good at all. They seem to like the 1,250 fps - 1,320 fps range.. Much past that and accuracy goes south. I use AA#9 on the Xtreme because it helps keep setback to a minimal and is pretty accurate. Keep in mind this is all from my particular set up, XDm .40 S&W 4.5" with a Storm Lake .357 SIG 4.6" conversion barrel.

It's only a 10 yard gun for me. Do you think Longshot would OK with extreme bullets and Speer gold dots as far as accuracy goes?

Should be good with the Gold Dots for sure. When I say Power Pistol is more accurate, its not like 1" group at 25 yards vs 3" group accuracy, but it is slightly more noticeable. I think it comes down to the velocity difference just like with any gun where the velocity node is at. If you keep the loads lower towards the starting load for the Xtreme they should be pretty good for that range. The thing with Longshot is that is is FAST velocity with lower pressures than most powders, same goes for Power Pistol. Since you have a chrono, you should be able to tell what range they shoot best at velocity wise. I'm gonna bet they like it similar to what my experience is. The Xtreme are cheap enough to plink with all day, so at 10 yards, it doesn't really matter if they are 1,200 fps, or if they are 1,500 fps. Find the most accurate load and tear up some targets having fun. You will find, you will probably never buy factory ammo in the SIG again because even FMJ are expensive LOL

Got it. I'll be testing away. [emoji106][emoji106]
