    My M1A likes this.

    42.7 gr WW 748
    155 gr Sierra palma match bullet. Max recommended COL

    One little bitty hole.

    It is a NM rifle rebarreled by Springfield with a Super Match barrel. Sorry I can't recall the twist rate.

    Check current Sierra manual before using this!!! Sierra has drastically reduced the MAX 748 charge between their 3rd edition and 5th edition manuals..[?]When I asked Sierra about the change I was told the most recent 748 powder they used was a very hot lot. I guess they use what they have and run with it.
