I just bought a box of Remington 50gr HPs a couple weeks ago for that very reason, I put a AR Varminter together and wanted to try them out, I wasnt able to get very much feedback on them in other forums though, I heard at one time that the American Eagle 50gr HP was a very accurate loading, the past 6 weeks or so Dicks Sports has had the Remington UMC 55gr MC stuff on sale for like 7.97 per 20 so I have been hitting that off and on for blasting ammo out of my ARs.
