I have my two "1894-1994" receiver stamped rifles: 30-30 carbine with checkered stock and 45 Colt trapper (my first CAS rifle). The 30-30 I removed the cross bolt and plugged the holes - it looks nice. The 45 Colt has the "John Wayne" loop lever. It's just cool.

Soory to chime in late as I don't frequent the Wire much - I meant in my post that if you have SPG or similar libe in the grooves of the projectile you are fine for many many years. Load 'em up at age 18 and shoot'em at age 108. Same affect. it's the lubed wad that might cause inconsistent ignition over time.

They will last forever (no lubed wad, SPG or similar in the projectile gooves). Nose down storage is always good, but if stored in a cool dry environment it should be no problem however they are positioned.
