[QUOTE="IdahoCTD, post: 754265, member: 13110"] I built a 6WSM on a Mcgowen barrel about 8 month ago. It shot pretty well but the velocity wasn't what I hoped before I saw pressure. 3450fps with a 105 Amax was about max with any kind of accuracy. I shot Retumbo and H5010 in it mostly with the nod going to Retumbo. R-33 would probably be a better powder because you can load 3-4grain more of it then Retumbo and the velocities are pretty good in my 6.5-300wm. [/QUOTE]
