Get a good slug gun. They are really effective on deer and don't carry as far as a regular rifle does. If you hunt from a tree stand your rounds will be going into the dirt and slugs aren't as prone to glance off as a bullet is. The same can be said for muzzleloaders.

Or, you can invite me to come help and I'll provide the guns and the ammo. I'm always willing to help thin the herd and don't have anything going on since I retired.
