good to here about that gun I have been curious how it will shoot, You seemed to be concerned about putting the bullet in a particular spot while testing loads know need to do that to test different loads just aim at your bullseye in the same spot each time with your 300 gr. then do the same with a new terget for the 250 the important part is group size so no need to use kentucy windage just shoot for group, once you decide whitch is best then adjust scope, and your done. 1 inch 300 yards is good , I like that. good shooting
