NO SUCH THING AS 'JUNK BRASS'...
If it's BRASS, it's worth picking up,
Just the 'Scrap Weight' makes picking up Rimfire rounds worth while since the weight adds up quickly.
Pick it up, If it's 'YOUR' caliber or not,
If it's in good shape, it's worth picking up since it quickly becomes 'Trading Material' to get what you want that cash wouldn't otherwise buy.
I still throw away steel cases, but I've started an 'Aluminum' scrap bucket, and between 'Starbucks' cans and aluminum cases it adds up pretty quickly also...
CONSIDER CASTING YOUR OWN BULLETS.
ANY LEAD IS GOOD LEAD, and casting your own, especially for handguns gives you a ready supply of bullets.
The old 'Cowboy' guns all use lead bullets, and they are a TON OF FUN to shoot and easy to load for.
I'm not a big fan of cleaning lead out of bores, but if it keeps me shooting and grinning, I'm not that lazy (Yet...).
PRIMERS LIVE A LONG TIME!
Just keep them air tight until use,
And rotate your stock, oldest used first...
Pick up bulk primers when you find them for a reasonable price,
I used to think 'Old' primers were 'Inaccurate',
But having to use some recently that were almost 10 years old,
Not one misfire, just as accurate as the 'New' ones, I've changed my mind.
