I used to think I could shoot 'well enough' for any big game situation. After a few frustrating years of either missed shots or my personal limit on range I realized I was lacking in skills/equipment to make the best shots and make them count. Started going out with a varmint rifle and shooting prairie dogs as often as I could and as much ammo as I could load up. Lots of shots, small targets and varying distances. I got very good at not only judging distance but making center mass hits. Virtually eliminated 'buck fever' and my confidence is over the top. Looking at a buck deer thru a scope at 400 yds.looks like the wall of a barn from 25 yds.
