I've always called the 300 WSM the 30-06 Ai +P grin

Nosler no.5 has 30-06 Ai data and shows 2,985 with a 180 and 62.0 of RL22 (24" bbl.)... however, all the other 180 loads listed with other powders are below 2,900, and it doesn't list any 165 over 2,950 which is kinda strange given the RL22/180 load.

Doesn't JB have some sort of formula to determine speeds of Ai's over their parent case?
