43.9 grains get me 2,751 fps from a 22" barrel with an S-D of 11.0 and an E-S of 24.
BTO (Sinclair) of 3.055" and a OAL ~2.790"

Will be testing this out on next season's Elk.

Question, how can your BTO be longer than your COL?
Just a guess, but his BTO may include the 1" of the Sinclair nut (assuming it was the nut type of comparator).
