The best source for j-word loads is probably on 300blktalk.com I have done 16.8gn of Lil Gun under the 147's and they worked well enough in both my AR's.The 300blk is an easy cast boolit cartridge and a number of us here have worked up combinations that work well. Use the search.
My pet combo is a Lee C312-155-2R boolit with Hornady gas check sized to .310 with Tac#1 lube on top of 17gn of Reloder 7. Custom PTX is used to open the neck to .308 and impart a small flare during case powder charging. Seating and crimping is 2 steps and a Lee FCD is used to give a light crimp in the crimp groove. This combo works well for range work and wild hog hunting.
