looking for a starting point/data. using hornady brass and 105 and 109 bergers. Thank you in advance.
6gt N140/ N150 starting point?
- Thread starter briang7511
- Start date
N140 ended up being too fast for me in alpha brass. Overpressured before speeds. But I walked it up from 30 to 32.
If it helps, N150 at 32.5g under a 109 hybrid was 2798fps and 33.5 was 2852. This is a 26" barrel with 2700 rounds on it and I'm jumping .090", hornady brass and cci 450 primers.
definitely helps, thankyou! recently picked up both N140 and N150. not alot of data out there with these powders.
Load data from Berger. N150, 109s, coal 2.58", 26" barrel 7.5 twist and cci 450 primer. Start 31.1 @ 2633 and max of 34.2 @ 2831.
