Word from Springfiled is Superformance is "ok" in modern M1As but not so much in old ones and Garands. I've only put 5 rounds thru it because the zero is almost the same as my 150gr plinking ammo.
Oct 20 this year, that deer was Oct 25 last year. And those are flies, it was about 11pm and 75 out so the flies gathered quickly. Thank you much sir!
