Sometimes I get asked, what's the best rifle/caliber/bullet for deer hunting?
That's easy. Deer are fairly easy to kill. A good deer is about the same size as a good goat and I've killed goats with a knife.
The plain fact of the matter is that whitetail deer have been killed with virtually every caliber known to man. Whether it's a fast stepping .22 caliber, or a massive .45 caliber, you can kill a deer with it. Ethical hunters don't want to needlessly injure a game animal, so they try to pick calibers with enough power to do the job cleanly. Certainly, the old .30-30 is a capable deer cartridge, as are any of the .30 caliber cartridges. As are the 6mm calibers, the .25 calibers, the 7mm calibers and all the rest.
Deer are fairly easy to kill, if the hunter can place the bullet in the vital organs. So, the requirement is that the ethical hunter must be able to place the bullet where it will do the proper job.
It's late August and in most places the regular gun deer season will be opening in about eight weeks. It's time to tune-up our sights and make sure that we can hit the game properly for a fast, clean kill. In short, it's time to get to the range.
After a quick session on the bench to verify your zero, get away from the bench and practice with normal shooting positions. Standing, kneeling and sitting. If you can only afford one box of ammunition, use five to zero the rifle, use 10 to practice your positions, and keep the remaining five rounds for the game fields.
I bet you won't need any more ammo than that to bring home the venison.
