357 Sig load data

[lakersfan]

Got some 90 gr XTP. Load data using Longshot powder:

10 gr max for 115 gr XTP
8.3 max for 124 gr XTP
7.5 max for 147 gr XTP

I'm thinking 12 gr would be ok for a 90 gr XTP to start with?

I wouldn't guess you'll get anyone here to buy into that thought. Stick with known factory data until you start to experiment slowly increasing powder charge.

This might get you pointed in the right direction

I used the max load data for a 115 gr XTP so far. Its ok to use data for the next heavier bullet but the trade off is similar velocity and less pressure. I'll see how these do then work them up if needed.

Reloaded so far...

65 rounds 115 gr XTP @ 9.7 w/ Longshot
66 rounds 115 gr XTP @ 9.0 w/ Longshot

94 rounds 90 gr XTP @ 10.0 w/Longshot

104 rounds 125 gr Montana Gold FN @ 11.7 w/ Accurate #9
86 rounds 125 gr Montana Gold FN @ 12.7 w/ Accurate #9

8 rounds 125 gr Montana Gold FN @ 13.0 w/ Accurate #9

If I don't get called in for work friday I will go to the range and test them out using my G32.

Out of bullets. What should I get next? Nosler JHP? Speer TMJ/GD?

My accuracy load, even out to over 100 yards on steel. Have fun.

The Montana Gold loads gave me the best accuracy so I'm gonna stick with those. Got a sqib when using the 90 grn XTP rounds so got it out and continued. Shot 450+ rounds at 15 yards, 6 mags were 9mm. Forgot to take a pic of the target. Too many low and left so need to work on pulling the trigger straight back.
