How many rounds will fit into a Remington sportmaster model 512?

Answer 1

Well, it all depends on which rounds you want to feed into the tube magazine. The Model 512 will shoot .22 short, long and long rifle cartridges, so if you put a mixture of .22 caliber cartridges in the magazine tube, the number of cartridges it will hold will vary. You can add one more round if you include a cartridge in the chamber.
