I have a bunch of 30-06 165 gr. ap rds I bought several years ago and they don't seem to shoot as well in my Garand as they used too . I hadn't shot gun or ammo in 4-5 years and decided a couple months ago to get it all out and play . Groups were 4-6 inches at 100 yds and this is about double the group size I used to get with this ammo . I bought a collet puller and pulled the bullets . The powder is some sort of ball powder and some of the rds had to be bunped with seater to pull . So I have several questions , one , what sort of powder do you think it might be ? Cases are marked L C 53 headstamp , Box is white with green label , yellow letters and states it is 30-06 black tip , 165 gr bullet non corrosive , boxer primed , new unfired U.S. military brass , manufactured in the U.S.A. I am assuming it is probally reloads ? Any way I tried reloading them in original brass with some H4350 and IMR 4064 , hoping to get maybe sone two inch groups . Am I expecting to much from an ap bullet ? With some Fed Eagle 150 gr FMJ's I have occasionally gotten groups in the 2-3 inch range with the Garand . Thank you , Kenneth
