Locally Wally World pushes Federal bulk pack 550 rounds for $19.97. (I prefer the copper plated/jackets that Federal uses to exposed lead). Plus tax, of course, but no shipping. Has been functioning well in all of my guns, S&W M63 and M17 revolvers, AR-15 with dedicated upper, Ruger 77/22, 1911 Colt conversion unit and Remington 513T.

Recommend avoiding Remington rimfire stuff. Lots of duds.
