Over the years I have heard various camp fire wisdom about rimfire longevity. Some folks insisting they will expire on the shelf after XX number of years because they don't seal out moisture while other folks insist the rim prime is more durable and smokeless ignores moisture, for the most part. I've used rimfires that have lived in Florida for 50 years or more and they still go bang about as reliably as new shelf stock... I've also had whole boxes go poof or refuse to fire at all. Anybody care to share their own camp fire wisdom on rimfire longevity and proper care? Seems to me the biggest factor for poof vs. bang is not moisture but rough handling and compression. I've noticed (purely observational anecdotal evidence inserted here folks - grab yer salt licks!) it seems like the boxes that look like they've been crushed, dimpled tops from bullet noses, etc. go poof most often.
Seems to me that basic storage conditions are all that's needed. Keep them dry and in a temperature range that is comfortable to a human (room temperature -ish).
When I got back into shooting with my kids, I had bricks of 22LR from high school and from my dad that were over 25 yrs old. We had a fun time sending it all down range. Recently, my boss moved to a new house and found a box of Thunderbolts and a sleeve of Mini-Mags in his basement from the 90's. Sent them all down range.
The only issue I've seen on old 22LR is some manufacturers used a waxy lube that would dry out and turn to powder over time. I suppose you could wipe them off and re-lube those. I haven't had that problem with Remington, Winchester, Federal or CCI.
