I would think that trying to make up for poor shooting by using a magnum is only going to make your poor shooting worse, and result in missed, or worse, wounded game. A deer with a 100 gr. .243 through the lungs is going to be a heckuva lot deader than a deer with the latest 180 gr. .300 Super Duper Mag. through the guts. I'd much rather see someone who is proficient with a light-recoiling .243 on my lease than someone who closeshis eyes and prays when he sets off a round from his magnum.
