I know its probably still hard to find specific primers, but try R 7.5 in the RL15 and in the TAC, it might cut the groups even more.

All the testing I did for yeras I only ended up using 6.5 R one time.

Doens't mean things won't work fine wiht the 6.5 for you but its worth a try.

Really WWSR are the ticket but they are too sensitive to use in an AR, with those powders. IMHO

We can keep Larry Root and all his idiotic blabber and user names on here, but we can't get Ralph back..... Whiskey Tango Foxtrot, over....
