Hello to all, this is my first post. I was breaking in a 22-250 today. I used a fairly mild load of a 55 grain Ballistic Tip and 38 grains of 760. Sticky bolt, shaved head brass, the works. Velocity, however, was low at 3350 fps, average. I think I may have seated the bullets out too far, but shouldn't a spike in pressure give a higher velocity? I used to run the same bullet and 39 grains in another rifle I had. Speed was 3550 fps, cases lasted forever. If my speed was higher I could understand it, but pressure with low speed has me scratching my head. Any suggestions would be appreciated.
