[QUOTE="fireworks, post: 842340, member: 70656"] Well I think I dialed it in. This gun likes the berger vld 150 gr. at 56.5 gr. Imr 7828 ssc at 0.020 off. 3 shots at 100 yds. You can can cover with a dime. One shot was actually partially inside one of the others. Not bad using a prone position bi pod. When I added up the three chrono's and devided by 3 the mean FPS was 2912 with a 22 inch barrel. I tried bumping to 57 grains and it started to separate and the mean FPS was not much better. Then I tried the 150 gr. Nosler ABLR. Ironically. The lands are virtually the same as the bergers so I went with 0.020 off as well but since they are a longer bullet I backed off to 56.0 grains. The group could be covered with a quarter but the wind was also picking up. Couple that with the fact I was again shooting prone off my bi pod I figured good enough. Here is the real irony... mean average FPS three shot group? 2912 same as the bergers? Go figure. I believe I could mess around with the charge and the BOSS brake and get the magical 3000 FPS but I don't see much point. This I feel is very good considering the 22'' barrel. Time to send the data and scope to leupold. [/QUOTE]
