For blacktail which are about the same size, I settled on 150TTSX with the -06 or 308.
For about a year or so, I've been experimenting with the 150 TTSX BT in a couple of .308's, three .30-06s, a .300 H&H Magnum, and a .300 Winchester Magnum. It shoots very well in all of them.
Surprisingly in the .-06s, I've gotten better accuracy with H4895 than with my long-time favorite '-06 powder, H4350.
