I'd probably simplify things and spend more time on hunting trips and shooting games (trap/skeet, defensive pistol, etc.). Of what I currently have: I'd keep the 22 K-Hornet for the small stuff, 6.5x55 for medium critters, 9.3x62 for bigger, and a 12 guage would cover long gun needs. I'd probably have to keep a handgun or two - a 1911 45acp and single action 45 Colt or 44 Spl. Then I'd have to keep something in blackpowder - don't think I could part with the Shiloh Sharps. Of the military styles, I'd pass on the M1A and keep the M1 Garand and Colt AR carbine.
That would get it from over 50 to under 10 and I doubt I'd miss any of the others.
