Re: interpreting ladder test - need help!
Except for shot 7, they're all inside 1.1 MOA. I don't think that's too shabby at all for all those loads shooting that well at 200 yards. Increasing charge weights typically makes bullets print higher with each one, but you gotta shoot 'em at long range to see that happen. Your loads don't do that; the ideal charge weight's somewhere in the middle of them. But that's a good example for just metering powder for shorter ranges; exact charge weights are not needed for good accuracy at ranges 300 yards and less.
Shots 5, 6, 7 and 8 go into 0.85 MOA. I'd shoot 10 rounds with 54.7 grains (about mid point in these shot's charge weights) and bet they would shoot very well indeed.
