Shooting some 340 fmj's fletched them myself, out to 30 there spot on but out to 40 there a foot to the right, grouping is good, is it possible my arrows are drifting between 30 and 40? or do you think its some other issue? I am also shooting fixed broad heads.
Where are they shooting at 20yds??? If they are to the LEFT, then you need to walkback tune your rest.
