This bull was killed with a 60# Hoyt and a 400grn arrow. Im pretty sure it died faster than any elk I have ever killed with a rifle. The fact of the matter is who gives a crap of how big of a caliber you shoot, I personally think there is no perfect elk caliber out there but on there other hand if you can shoot any big bore rifle well kudos to you. Being a bowhunter I have killed more elk with my bow than I've had with my long gun. The first cow I ever shot was with a 7 mag, I happened to walk right into the heard in the thick timber. I picked out my cow and @ 40 yards I squeezed off my shot. The bullet was a 150grn Swift Scirocco, she ran a total of 75 yards or so and piled up. My very first big bore I bought was a 300win back when I was 15, I got the living sh** kicked out of me with that gun and it made me very trigger jumpy. I soon sold that gun and bought a Ruger M77 in a 243win. I learned to shoot that gun well and for the past 10 years every deer that I have killed has been with that gun, I know where its gonna hit when I squeeze that trigger. I wouldn't hesitate one bit on killing an elk with that gun, call me a dumb ass but thats what I prefer to shoot. So who really gives a shit what your buddy's shoot if you know your rifle and you are very confident shooting it use whatever you like.
