Home Forums Hunting & Shooting Elk Hunting Which Rifle to Take?

I was just notified that I was chosen for an Elk (cow) tag by the State, I am looking for any tips or guidance. This is my first Elk hunt though I have hunted Mule and White tail deer all my life. I am 82 years old and am working on getting the legs in shape. The terrain is mountainous but nothing like the Rockies. I will be using a 45-70
Marlin Guide Gun. What weight bullet do you recommend and has anyone tried the Hornaday Leverution?

Thanks for any help or tips,
Walt
