The .22 doesnt foul very much.
.22lr ammo leaves guns filthy.
After 100rnds, the action in a 10/22 looks like you dumped black powder directly into it.
I don't clean my barrel other than using a bore snake.
However, after each shooting, I remove the stock (one screw), remove the trigger group, bolt, and bolt handle (3 pins), and clean everything up. It doesn't take long at all.
There are a few exceptions like when I go small game hunting and don't shoot many rounds, I won't clean it. But if I'm ever at the range and blow off a brick... yeah it's gettin' cleaned.
