I'm having a problem with Speer 62gr FMJ BT, running through a 1/9 twist 20inch barrel.
What I've tried so far is;
23.5grs IMR 4895, best was 2 moa
21.5, 22.5, 23.5 grs H322, best was 21.5 for 1.75 moa
18.5, 19.5, 20.5 grs IMR 4198, best was 19.5 for 1.5 moa
All the above loads are with Winchester brass, and Winchester small rifle primers. C.O.L. was 2.250"
It was 0*, very light rain and very little wind, but I finished the day using my pet load with a .488 result so I know the rifle's doing it's job.
Any thoughts would be appreciated. If I need a different powder or magnum primers, I can do that.
thank you,
