Hi Richard, the R5 barrel of the M24 sniper rifle is designed to be used with the 175gr Sierra MatchKing. That said, the 1:11 twist works well with many bullet weights. I have been able to get a consistent .250" with the 168gr A-Max in the most recent R5 I tricked up which I believe was from the same batch as your rifle.

I answered a similar question today in the long range hunting thread for Matt Reid regarding a decision over which A-max to use for long range work. Have a read and see if it helps.
