    Bought these from this site way back.

    Shoots sub-moa on a Remington 700P 26inch 1/10 twist. “Easy round”, I’m not super skilled but wind hardly effected this 220gr to the point where it was “easy” to keep a tight group at 1km despite moderate cross winds.

    I’m no gunsmith but the last few rounds I shot were still sub-moa (100rd in total thru the barrel). These rounds are quite more powerful than your typical 300winmag rd and I don’t know how many of these rounds will effect the life of the barrel.
