22 hornet is a 22 calibre rifle. Most think of a 22 rifle as a rim fire rifle. But it shoots a 22 calibre bullet but the cartridge case that fires the bullet is no where near the same. The Hornet holds much more powder and is center fire.
IF THIS RIFLE HAS 2 BARRELS ABOUT $200 IF ITS AN OVER UNDER COMBO GUN ABOUT $300
Single shot break action? yes.
In short, no. I have a single shot lever action Ithaca rifle, and a turn action Garcia Bronco .22. There have been auto ejecting single shots, and a LOT of bolt action single shots. The "trapdoor" Springfield rifle was not a break action.
A single shot .22 rifle. Bolt action
Single shot bolt action .22 rifle.
The 22 Long Rifle has different size cartridges, But the 22 Hornet has pictures of deer killed with it. The 22 Hornet is a lot more powerful than the 22 Long Rifle. They both have different grain.
