Your assumption that the 265 grain bullet will be going slower isn't necessarily correct. The 265 grain bullet (I'm assuming it's not a ball...) will take up more space in the case, which will result in more pressure and quite possibly a higher velocity.
My Lyman manual shows a 185 grain bullet doing 1191 FPS with 9.5 grains Unique and a 210 grain bullet doing 1197 with the exact same charge. The pressure on the 185 grn round is 32,800 vs 39,000 with the 210.
However, if some how you are shooting identical sized round balls the heavier one will be going slower.
