Haven't gotten a chance to use any on game yet, but I've shot several out to 500yds at an 8'' piece steel. We were shooting the same 125gr Nosler BT through a 20'' .308 & a 16'' 300BLK both of which were mdl700s. Surprisingly enough the 300blk had no issues ringing the steel consistently...ballistics calculator says it's still super sonic at that range. Used Varget, CCI 250 mags, and lapua brass for the 308. I also had a soft-ball tied to a string, hanging at the same distance...I don't know how many inches across they are, but the 308 was noticeably better at hitting it. Could've been the scope/shooter of course.
