I tried a variety of powders today with 110gr, 147gr, 220gr and 240gr bullets. The supersonic loads all ran great and I'm going to need one more port for the gas to reduce the high vel loads ejection. The 240's were ejecting and reloading fine but would not lock the bolt back on the empty mag. I'm happy with it now and will get the painting done. I was surprised to find that the faster powder actually seemed to do the best job. I tried 2400,N110, H110, 4198, and Benchmark. The best overall was the 2400 with 9 fps max variation for 3 rds 147gr and 11fps with the 240gr monsters. I had the 110gr round nose tracers(M1 carbine pulldown bullets) zipping out at 2150fps with room for more but on the small port ejection was dinging the brass pretty bad. With the 240's 4198 was really good but the benchmark was not. I only fired one round as the bullet stuck right at the muzzle. I think thats the limit for slow powders. Bullet pushed out easily with no damage to the barrel. Things are getting figured out and this is one sweet little rifle. Barrel length is 9" so I'm not sure how much of the info will carry over to my 16" bolt action and now I have to keep separate brass piles etc but its worth it.
I'll post more pics when I get some proper paint on everything.
