Have you ever owned a magic rifle?

My 'magic' rifle is my M-1 Garand. When I bought it from CMP about 20 years ago, I took it out to my 100 yd range and was seriously disappointed that the smallest group I could get was 8". I finally tracked the problem down to a very slight ding at the muzzle, making the muzzle slightly oval instead of round. I used a tubing cutter to mark a ring 3/16" back from the muzzle, then cut it at the ring with a Dremel cutoff wheel. Then I borrowed a crowning tool from a friend and crowned it. Problem solved! Now it shoots 2" groups at 100 yds with iron sights. I took it to Whittington Center 5 years ago and was hitting the white buffalo consistently at 1,123 yds using Greek surplus ammo from 1976 - 77. That pretty much convinced me that if I can see it, I can hit it out to 1,123 yds.
