They made them in four calibers. 25 Remington, 30 Remington, 32 Remington & 35 Remington. The 25 & 32 are obsolete, the 30 was still available in the 80's & the 35 is still available at your larger sporting goods stores. There are dozens of custom reloaders that will still supply ammo for any of these calibers.
