As I hav posted before, I got "pd" a brick of 22 shells a wk to feed cows in the winter. I have a 10-22 I got in 1971. I hav shot 10's of 1000's Rem Thinderbolt, Mohawk, and Federal Lightning. When my rifle got dirty I would generally spray WD40 olin it and keep on shooting. I remember these shells being $5/brick at WalMart and that might hav been a sale price
