My long barrel ones will only fit in one of my safes - a 30 gun Browning safe (tilted clockwise). Others are in other safes, lockers, gun cabinets, closets and attic. Most are in Midway silicone treated gun socks which have worked well for me, but it's hard to tell what's in the sock by "feel". Some that I shoot from time-to-time are in the garage safe. Others are ...well ... around here somewhere. Some I've not seen since we moved in '04. Some I've not shot since the '80's.
Those I've retrieved from the various "nests" prove the wisdom of cleaning properly and applying Hoppe's gun grease to metal parts.
My last old-time M/L buddy's now in assisted living, the rest are all dead. Thanks to this forum, my interest in muzzle loading's revived.
Gotta do an inventory....and get more Hoppe's gun grease.
