I load 150gr Gameking and 155gr Palma SMK with 50gr of IMR-4895 which gets me just over 2900fps and accuracy is under moa if I do my part.
My 30-06 loves CorLokt and I shoot them if Im not shooting my handloads. I havent shot any heavier bullets than the 150-155gr. I havent hunted anything that required anything heavier.
Sometimes I load 48gr. of 4895 which puts me at around 2800fps for just target shooting and plinking.
