Being able to shoot tight groups on the range, is good thing to be able to do, but often,very often, does not translate into a GROUP of ONE in the kill zone ,of a LIVE animal under hunting conditions. If you really want to get serious about increasing your skill at taking game-- practice by hunting squirrels. With squirrels you either kill em or miss em, so you need not be concerned about wounding them. Its a whole different deal, to draw and shoot accurately when you know the target has the ability to see you and move before you get the shot off. Targets, i.e. 3D, are not so good at seeing you draw, and then running off.--You may have noticed this. There is nothing that can substitute for live targets for hunting prep. Squirrels, are wiley, plentiful, and fine table fare. I prep. for every deer season w/ at least 50 hrs. of squirrel hunting. This will make most deer shots,seem like lay-ups.
