Went out today and did some Tightgroup with Campro 405 gr plated bullets. Starline brass that I annealed first, CCI large rifle primers.
Range was 50 meters. New production Winchester 1885 rifle for testing. I shoot 405 gr remington bullets with IMR4198 out of normally, at 100m it's 1.5" or better usually. I'm the weak link.
I loaded extra at 10gr for sighting purposes, I figured I'd have to raise the rear sight due to lower velocity. I was wrong, had to bring it all the way down to get on paper . All groups are 7 shots, can't remember which reloading manual said that. I've always stuck with it.
I will load more and go to 100m and see how they group. I'm pretty happy with results so far. If they hold under 3 inches at 100m I will be happy. Inexpensive to shoot and quite.
