Re: 6mm AI
I'm shooting a 6-284 and having outstanding relults with Ramshot Magnum.
It is a great powder for the big 6's.
Shooting the 107smk's at 3400fps with very low sd and es. of 8fps and only a couple inches of vertical max,at 600yds. Some of that could be me too .
I put my last two out of three shots into one inch at 500meters with the 3rd just two inches away directly horizontal, must have been a gust of wind.
Ramshot Magnum is a much underrated powder.
