wesh

purchased a ri 270 wsm a few years back. tried a number of different brands of ammo and grains. haven't been able to obtain a good grouping. have always shoot fed. premiums in my old 270. 130 gr. nosler partition. worked great on dear and 150s for elk. noticed the new r1 does'nt come in the 270 wsm and fed. ammo. is'nt making 130 gr. nosler any longer. any ideal why? also, any recommendation on obtaining a better grouping?
