Have you shot or hunted much lately? If not, and you have that many rifles and kept them in crates, does it really matter what you buy next?
Just cut up a list of cartridges, put them in a hat, and draw one. Or...just go out and shoot a few that you already have and enjoy them. You're a very lucky guy and don't even know it.
If I can't be with the rifle I love, I love the rifle I'm with!!
