I bought a crap load of 64gr Nosler bonded from Shooters Pro Shop with that very thought in mind, iirc they were 25 bucks a hundred then, haven't hit anything but paper, suppose they'll do fine leaving at 2776 fps over Alliant Varmint and CFE-223 from 7 twist 16" mid length AR's.
I have several hundred of those as well. Never fired any. You sticking to Nosler data on n CFE223? My 20” AR is on the verge of birth and I just might blood it in November.
