BigPapa Posted September 9, 2015 Share Posted September 9, 2015 Well this Saturday was my first USPSA shoot and my first go at reloading 38 super.For the shoot I reloaded all my 38 super to about 1250 fps (Chronographed) using 115 JHP as well as starline rimless brass. This was with the maximum powder the manufacturer recommended.I was told during my shoot that I need to reload well above the manufactures specified values.I currently have an Open gun and need to hit Major Power Factor; 165 I believe.I was wondering if anyone would give me some pointers on the best powders, bullets, and primer combinations. From what Ive read I should use a light bullet (JHP prefered) with a slow burning powder as well as use small rifle primers due to the increased pressures of the minimum 165 power factor. I'm adding pictures of my gun and barrels since it appears the porting orientation seems to make a difference. It would appear I need more posts before I can post pictures, but I have an STI pistol with 2 ported barrels. The first barrel has 3 large ports on top and 1 small verticle on each side near the rear. The second barrel has 4 large ports on top, as well as 2 small round ports near the rear. Has 2 verticle ports on each side near the end of the barrel. I'll post as soon as I'm able. Link to comment Share on other sites More sharing options...
