My son presented me with a surprise gift - a custom long range rifle in a favorite cartridge 264RM. After the initial shock I spent some time working ulna load, the gentlemen who built the gun had used a load to verify the guns accuracy so that was the starting point. The gun settled in liking 61gr of 7828 sc behind a 140 gr Berger VLD. This was the first time I ever had three rounds touching. Just in time for deer season thanks Son.
