Thanks for the input guys, AK that is a way cool site for the hard to find data. Vapodog, have you tried any loads for 150 gr bullets? The factory loaded 180' s that I had were a little stout on recoil, not that I' m recoil shy or anything it' s just that that load kicked harder than my 06 with 165' s. I realize that not many have any experience loading for the 307 win and data is just as scarce. Any other input is still welcome, once again thanks.
