The best load for my Rem 700 .30-06 I could ever come up with was the 165 Sierra BTSP over 48 grains of 4064. Couldn't tell you the COL, but it was as long as I could make it and fit the magazine and chamber without touching the rifling. When conditions were right and I was steady, sub-MOA 5-shot groups were not uncommon. The bullet's performance on game was faultless at all ranges.
