Ammo for a combination gun
Most combination guns pair a rimfire barrel with a 410 barrel, so you need both. Check the markings on each barrel, then shop 22LR Ammo or 22WMR Ammo for the top barrel and 410 Shells for the bottom.
Combination Guns FAQ
Do I load both barrels at once?
You can. A selector on the hammer or frame chooses which barrel fires, so you can carry one of each loaded and pick the right one for the shot.
What are combination guns good for?
Small game and pests at short range. Use the shot barrel for birds and moving targets, and the rifle barrel for a still squirrel or rabbit.
