SD: 6@James:
Use any book data for N320 that you have for 115 grain jacketed bullets, start at the lowest end. You can use the same OAL I used above, 1.075, but I\’ve run these bullets as long as 1.10. Keep in mind, that their profile is not conducive to guns with a short throat if they are loaded long. As long as you start at the minimum charge, and test as you work up, you\’ll be fine.Eric
Thanks I started with 3.5 grains of N320 and worked my way up 3.8 and worked great with a oal of 1.10 to 1.116. At 3.5 grains I had one stove pipe out of 5,at 3.7 I had 2 stove pipe out of 5 ,at 3.8 and 4.0 grains all rounds cycled fine. will be checking the cases for over pressure but at first look all looks good. Once again thanks for the helpDouble post. I missed the existing section for the 115MPR. Apologies…
