[QUOTE="toyonrocks, post: 777404, member: 35433"] Been playing with these guys in my AR for a while now. I feel the same as you I guess. Some days I feel like I'm getting the results I want with all rounds touching on paper and measuring less than .5" groups and other days I get flyers and get disappointed with my pet. But I use the 69gn BTHP seated at 2.269, cause the mags absolutely won't allow any longer seating depth, 24.8 gn of 748 and CCI BR4 primers. Guns a bushmaster varmiter with a 24" bull barrel at 1-9 twist. It's on the slower end and I kinda think. Never actually run them through a chrono but I'm thinking just under 3000/fps. That seems to be the ticket. I'd really like to make a faster round but with all of my trips to the range it seems that I get lots more flyers and lots of spread out groups if I do. I shoot off of a bi-pod and bags from a table typically but borrow a buddy's lead sled now and again too. If anyone has ideas that could tighten up my groups I'm always up for trying something new.... [/QUOTE]
