Alliant lists 62 grains with the 165 for 2725 FPS....and even less velocity with RL-19.....
Alliant has to have the worst loading data of all the powder company s.....I think even Ramshot is better documented!
I'll guarandamntee you that you can get close to 2900 FPS or more with the .30-06/165s and the right powder.....
As others have said....H-4350 is a good try.....also H-414
