Elk archery bow draw weights

[Dave2643]

I recently had surgery that left me too weak to draw my bow. I am 72 and have been fairly successful in bagging elk with a bow and still enjoy getting out that time of year. My bow was an Elite Hunter with a 70# pull. I am trying to regain my strength and have let the pull down to 60 lbs, which is all the local bow shop recommended I go. My question is what is the lowest weight of draw is an ethical pull for hunting elk? I may have to purchase a new bow.

I'd hunt with a 50# bow. Heavish arrow and a small cut on contact fixed blade.
