A couple of the hot local USPSA shooters are using N320 in their 9mm competition gun and recommended it to me as both soft shooting and accurate.
I thought I'd give it a try and have 4lbs en route
Looking on the Vihtavuori website in shows a range of loads from 3.9grs (.25g) to 4.3grs (.28g) to drive a 124gr (8g) Hornady FMJ/FN, loaded to 1.142" (29mm), out of a 4" barrel to 1017-1096fps. Interestingly they were loading RN and FN to the same OAL
Loading a 124gr cast bullet over 3.8grs gave them 1073fps; while 4.1gr gave them 1125fps
I'm loading the RMR plated 124gr FN for IDPA looking for about 1050fps...chrono'd out of a 5" barrel; so I thought I'd start at the cast load and see what the differences are.
Does anyone have experience with N320 that they'd like to share?
Any suggestions regarding charge weight or OAL?
