2520 test today was one hit, one swing and a miss.
Load for the '03 was 39.0 gr 2520 pushing Nosler CC 155's. Kinda sucked- hits all over the 9 ring, not really hitting the 10. Dirty, and the recoil impulse felt a little 'off'. I noticed the case fill was lacking for this load. Anyway, worth a shot based on a recommendation from one of the best shooters I have met. I'll pull the rest of the rounds and load them with Varget for Sunday. PITA, but Pembroke is a long drive to show up half-assed. So much for that poo-say load.
Load for the K-31 was 37.0 gr 2520 and the same 155's. Case fill looked much better this time. Results were very good- on below target I walked in the shots from the upper right, then proceeded to hold the 10-ring and X-ring. Gusty and crappy light at my range, so target might look even better if I was shooting better:
So the 2520 will be the go-to for the K-31. Semi-mild load. Still dirty, however. Might work OK for .308 but I'll stick with Varget for that.
