pop have you used the optimum barrel time calculations yet to set up any loads? I thought the guy was full of crap but its worked when i backed calculated five accurate loads in 5 diiferent guns. I think he may be on to something. I'm going to try it on my ruger 77 22-250 this weekend without having done any other load developement. If the load shoots good i may be a serious believer.
