WOW!! That is one WELL SHOT 10/22. I've always used the stock 10 round. JUST finally bought a couple 25's.
You must have 10's of thousands of rounds through those feed lips. Mine still looks new-ish, and I KNOW it has at least a few thousand.
Well done. When I see a motorcycle or gun or whatever, well used like that, it tells me a lot. You've had some FUN.
LOVE the 10/22. Was just talking about that with a friend. It's the ruger laminated stock with a $30 3x Simmons scope, and it has by far got more trigger love to date than any other rifle I have.
It is a Wood Chuck, Racoon, Possum & Skunk eating MACHINE.

Once they find the cat door into the garage, they gotta go.
That .300 will end them pretty much painlessly though. My 10/22 may get some rest.
Some say the 10/22 multiplies in a dark safe. I've stayed monogamous, but I understand why some would want more.
