A lot of guys these days deer hunt from a stand so gun weight is not much of a problem.Myself I like to hunt using Sharps rifles ,muzzle loaders and levers like the Winchester 1886 so carrying a heavy gun is a way of life for me .Like anything if you do it long enough you get use to it and it becomes second nature.Other advantages of a heavy rifle versus a light one is the heavy rifle is easier to get a steady hold from and doesn t make you flinch like shooting a stiff recoiling caliber in a light gun.The last one can affect your shooting for life if you subconsciously develop a flinch from doing this that stays with you even when not using large caliber guns
