I know that the 270 gr TSX and 75 gr of RL-15 will kill a 72" moose at 300 yds as well.
At least it did last week!
trapper, picture of the moose would be great!Congrats!
I watched last September as a pal worked up loads for a pre 64 M70 375H&H with 270 TSX and RL15(25" barrel).I recall he was hitting 2800 with the 270 gr but cannot recall the exact charge of RL15.
