Awesome advise above...
Keep in mind that 40lb is legal poundage for hunting, as long as you can pull and shoot 40 lb efficiently your good to go ...until you can pull more weight...
Worst thing I see is shooters over bowed...they teach themselves bad form and it effects accuracy...and when it gets cold they may find they cant draw bow!
40 Lb will take down bear, moose ,elk and deer with well placed arrow as quickly as a 70 lb bow
