If I had to minimize I'd cut back to arms I have significant ammo stocked up for. In my case that means .22lr, .38spl, 9mm, .556/.223, .308 and 12ga.
My arms choices in these rounds are:
-.22LR, Ruger 10/22 TD
-.38spl, I choose two here, Ruger KLCR for CCW and a Ruger GP100 6" as it's legal for deer hunting in Ohio
-9mm, Here I go with 2, my newest 9mm, A Glock G19 Vickers & G17 Vickers backup, main defensive arms
-.556, Tavor X95 as it's so compact, maximum performance carbine with minimum footprint
-.308, Ruger Precision Rifle, Big Daddy
-12ga, Browning Cynergy, 30" barrels, synthetic stock and full camo, super versatile shotgun
6 chamberings, 8 weapons.
None of these arms are budget pieces, they are all very good quality leaning towards higher end IMHO. But I already have them all and feel they are the most versatile and effective for my uses & needs. I figure what I get rid of will enable keeping these.
