As title says.

Montana Gold 125grn Sig JHP bullets. $123/1000

What are your results? Good choice or not? If not, what is your choice for bullets in the 125 to 135 grain arena?

Also, is 147gr too heavy for 357 Sig?

Thanks

I haven't tried those but I do really like Hornady 125gr HAP,they are bulk packed so a little cheaper,also Nosler 124gr JHP sporting handgun bullet,also bulk packaged.

I believe the bullet you asked about is this one, beside a Barnes 125TAC-XP. I use them very happily in my 357SIG-calibered pistols. They're lightly jacketed, as are all the inexpensive HPs I'm aware of, and hence aren't suited to Personal Defense, but they hold together at high velocities so are well suited for full-power practice loads.

The 357SIG will propel 147g. bullets lots faster than the 9X19 will, but I prefer lighter bullets for no rational reason.

What's your purpose with these loads? Practice? Competition? Personal Defense? If the latter, I use the overall-best (IMO, of course) bullet my money can buy, the Barnes TAC-XP solid-copper bullets.

I found the 'magic' powder for the 357SIG and this 125g. bullet (HS-6), producing high velocities (c. 1360FPS @ 10'), safe pressures, and very low muzzleflash...AND...it fits in the case under that loooooong bullet. :)

Less-expensive bullets well suited to PD are the Speer Gold Dot and the Hornady XTP. The latter is my favorite 'affordable' 124/125g. PD bullet. Gold Dot on the left, XTPs center and right.

I'll share some results ...

Glock Model 31 357 SIG...

Remington Factory 125 gr JHP Averaged 1375 FPS

Winchester White Box 125 gr FMJ Avg. 1353 FPS

Hornady 124 gr XTP, HS 6(W540) 9.0 grs Avg. 1338 FPS

Hornady 124 gr XTP, 800X 10(C) grs 1503 FPS

The 800X load is a compressed load, which helps with bullet setback that can happen with the 357 SIG. 800X does not meter very well as the flakes are huge... each charge was weighted to be dead on 10 grs. This is a stout load!

All load should be worked up by reducing charges 10% and back up ...
The 800X is a set load do not reduce... it is reccomended only at 10 grains by Hodgdon

This is some info I posted in another thread...

I have not used the MG bullets myself....

Thanks for the input.

These will be mostly for practice.
