Default Mysterious phenomenon --cartridges expanded in size?

I recently found a 50-count box of .22 caliber, long rifle, 40 grams, lead, Lubaloy coated cartridges by Winchester in my dresser drawer. They are probably 10 years old. I tried to insert them into the cylinder of my old S&W revolver (a heavy "K" .22, I think).

To my surprise -- they didn't "fit" into the cylinder. The casings seemed to have actually expanded in diameter. I tried to a bit of gun oil on them, but to avail. I could probably pound them in, but that might be a big no-no.

Anyway, has anyone on here ever experienced or heard of such a bizarre thing?

And how does one dispose of unwanted bullets? Take them to a cooperating gun store for disposal? Take them to the police department? Bury them in the back yard? I don't want to throw them out with the garbage, as they might explode in the landfill.

Thanks in advance for any answers, comments or suggestions.

A newby

I do not think the case could "expand" with age. The bullet could, however, as the lead can oxidize and "grow". Compare one with a micrometer or good caliper to a modern/fresh round to see where the discrepancy is.

The .22 is a heeled bullet. The internal diameter of the barrel is the same diameter as the cartridge case and bullet.

This makes measuring the cartridge easy. Is the bullet the same size as the brass?

Does the cartridge hang up in the cylinder at the beginning or after the bullet is inserted and the brass starts to go in?

Two suggestions;

  1. Clean the cylinder with a chamber brush,
  2. Or, find a well used rimfire with a worn chamber.

Or you can do what G37 suggested and forget the $3.00.

Don't try to dismantle .22lr bullets. Should the primer compound in the rim get activated by using any tools, could be a trip to the ER.

With all due respect, isn't this "Much Ado About Nothing"...??

I'd say toss them and get another box, unless you like me live in Brazil and a box of .22LR hurts you for 20 USD for a box of 50. I figure a lot of things could have happened to them over time,....

Ahh and also, don't we owe Buckaroo the good ole' "Go the the introduction forum and introduce yourself" speech,....

Think about the possibility of maybe your gun got smaller?

Some muscles will reduce in size if not used regularly.
