So far, everybody is right....if the elk meat is hanging on the meat pole, whatever was used to put it there, was the correct choice. I have shot elk w/ conicals and PRBs and see no difference w/ either as far as killing an elk. Presently prefer the PRB ...not because of "killing power" but because the conicals come off the powder charge w/ a clean bbl and the trajectory of the PRB is flatter than a conical. Our "camp rifle" which is used by newcomers to our party, is a .50 using 410 gr. Buffalo Bullets and has killed a lot of elk but w/ the caveat to the user to periodically check the bullet seating. Again, I think a person should use whatever he feels confident w/ and the arguement of conical VS PRB is an exercise in futility....nobody's opinion will be changed......Fred
