First, yes I have searched and read everything I can on loading for the 7mm ultra. I have a new to me model 700lss coming in this or next week and this will be my first venture into the magnums. My longrange plan is to have a 270 Alan Mag built with this action, but that will have to wait awhile. With availability of components bieng somewhat of a problem, I would like to start out with some proven loads. It is a factory stock rifle with what I believe to be a 1 in 10 twist (26" barrel), am I correct in thinking that I can stabalize up to a 168g bullet? The Hodgdon site is showing us869 as the lowest pressure for bullets from 140g to 175g followed by 50bmg and then retumbo. Retumbo is what I've read most about on this site. Please steer me in the right direction. Has anybody used the cci34 primers for this case? I have a small stash bought for loading in my M1 but have not seen the need yet. I plan on getting a newer load book that has info for this, is there a particular book that has more or better info? Sorry for the long read, just trying to cover everything in one post.
