Re: In all honesty, how much better is a 6mm over a 243. win
Another advantage to either the 243 or the 6.5x284 is Lapua brass. The most accurate sporter I own and it is the lightest as well is a 6.5x284. The brass prep is the same as my competition rifles because the same reamer is used to chamber it.
My 1K load is 48.5 to 49.2 gr of H4350 launching a 142 SMK between 2940 and 2980 depending on outside temps.
