The .243 is still my favorite of all time. It's not my only, I'll never be without one.
I've killed more with a .243 than anything.
I was done after the 6.5x47, then needed to give the .223AI another shot since I read so much shit about them. Figured everyone needs a 6mm Predator, then decided I really had to have another 7mm 8400. That's not counting pistols. Yea, I've come to find out that being 'done' don't mean shit.
I'll probably have another sell-off in about a year, and start over like I usually do. But then again, I'm pretty damn happy with some of them I've came into over the past year.
