I have been using Fed210s for my 6.5-284 lately, but I don't want to count out other primers as well. I have some CCI BR2s also. Powders availiable are H4831SC and H4350. Got about a 4" group at 550yds today with H4831SC (49.5grs) 140gr JKL bullets and Fed210 primers, brass is Lapua. Was pretty happy with it as I haven't shot long range in over 2 years. I am always striving to do better as I am slowly getting back into this sport. Was just curious if other primers may help shrink group size or should I just stick with the trusty Fed210 primer. Any info or opinions are greatly appreciated.
