I don't very often these days for various reasons. But I'd say almost all of my collection is in working order or could be made so without too much effort.

I think not shooting guns in your collection is a perfectly respectable decision, especially if they're pristine. Having a near-perfect, museum-quality example is what many of us collectors aspire to after all.

If you're into shooting more than collecting for it's own sake, then by all means seek out good, usable examples and fire away.

Some, but not all, collectors seem to wear the fact that they shoot their collectables as a badge of pride. Not sure why.
