mine is at 68 i can shoot about 15 times then my shoulder starts to hurt i know a guy who shoots everyday like 50 arrows. NOw he needs shoulder surgery. He has never hurt it it just started hurting one day.
I would think you would be good out to say 20 maybe 30 with 50 pounds I think indiana's law says atleast like 35 or 40 pounds

welcome good luck and stay safe
