Re: .243 Win
Would opting for high density powder charge with 105+ weight bullets with 243 win offer best acuracy for 1k+ distances, Presently finding good results with 46g single based Vihtavuori N160, ccibr, Lapua brass, 105g moly berger VLD, The high energy version of n160 which is N560 seems to yield less repeatable acuracy with same components for some reason with my 243.
