You need to be able to draw hunting what you shoot routinely and easily during practice. Hunting, sitting still, being cold & stiff, in awkward draw positions means you will only be able to draw less bow weight IMO, at least up north here, in Wisconsin, during Nov. & Dec. etc.. When you sit on stand in temps. in the teens for 4 hrs. and a buck comes directly below you or other compromised shot scenarios, drawing your typical bow weight can be very challenging. If anything, practice with heavier draw weights and hunt with lighter.
In the summer, standing shooting on the level with muscles all warmed up, wearing a tee shirt and shorts, I can easily draw 15% to 20% more bow weight than I can hunting…and I bet you can too!
