I found all my rifles will shoot 2 moa or 1/2 moa
I found this by doing a ladder test
by weight
if they didnt shoot 1/2 moa -then I could have backed them up & played with coal
but most all rifles shoot better jammed or .10-20 off the lands IMHO
it took less than an hour for each rifle
I dont ever have to do it again
unless I choose to shoot a different projectile
then it'll cost me another hour of my time
I didnt go .2 grains at a time - I went a full grain
only on one of them- I had to go 1/2 gr on either side of best whole gr to dial it in
ladder tests - it worked for me
