Im in my 5th can of blackhorn and ive just started shooting without the FPJ on the last can and a half with no problems. Ive just been seating my sabot with normal pressure also. Cleanup is so much easier without the FPJ, ive shot groups both ways, and it doesnt change accuracy. So all my range time will be without FPJ , and hunting will be with FPJ. Ive tried both primers CCI209M and federal 209A to compare groups also, after MPARKS thought primers might be affecting his accuracy, but it didnt seem to matter in my LRH. So im going with whatever is cheapest one.......... :lol:
