I usually buy the copper plated winchester 333, 555 or dynapoint from wal mart. I think a 333 box is $15, and the 555 or dynapoint cost around $21 a box. I like the copper plated ammo better, because I find it feeds better, and does'nt jam. Regular lead ball nose .22lr is really soft, and gets hung up easy, causing a feeding problem in my semi auto's. I like to keep a good inventory of .22lr, and rarely have less than 5-6 bricks..... Too bad canadian tire did'nt have any good sales on bricks of .22lr, like 60% off sales, like everything else in there store. Usually the only ammo sales at can tire, is on stuff that knowone buys
