I use the Hornady 52 gr BTHP in my AR. It is an excellent bullet. I can consistently get 3/4" 5 shot groups with them. I used them in my 22-250 also with the same results. I was using IMR 4895.
I'm currently running 52gr smk's with 25.5 grs of varget in my 700 tactical with a 1 in 9 twist.. shoots little bug holes at 100 yds from a bench. Shot a 2 in gong at 250 yds a couple weeks ago till it got boring.. This was after a thorough barrel break in, some may not see the need for this, but I'm a believer in breaking in a barrel before load development begins... JMO
