Gentlemen - - -> Also keep in mind that as in the above (Hodgdon),the loads are from a 1:12 bbl. That twist will handle a "little more" pressure than a 1:7 bbl.
I have never had a problem,with any chambering,starting in the books med pressure loads. Some load workups I even start fairly hot. Good example is a Win92,Ruger #1,or H&R Handi Rifle action.
NOT telling you to do this. This is just me. YMMV ---- SAWMAN
