Re: $4 a round to shoot!
For any of my hobbies, I never add up how much all the crap costs. If I added up how much I spent I bike parts, I'd probably have blood spurting out of my nose, and forget about shooting - that would induce sudden death. I just enjoy doing them and don't worry about cost, too much. Its not like I'm going to stop shooting, just because it cost a little more.
If I had to compute the cost of a pound of Elk, based on a realistic estimate, it would be like $600/lb, so you're damn right it tastes great!
Do yourself a favor and stop adding up how much all that stuff costs. Trust me, its liberating. It will take some practice, but its worth it.
If you like your hunting rifle, you can keep your hunting rifle.
