Get after those tin cans with your Umarex Canex and an extra 3-pack of 10-shot rotary magazines. Shooting the Canex airgun is super fun and even more fun when you load up plenty of magazines in advance. Just remember, load the magazine from the "gear" side (think "gear to the rear") with your favorite .177 caliber pellet and set them aside for when you are ready to use. This 3-pack will allow you to load up 30 pellets in total. Might as well get some extra 12 gram CO2 capsules while you're at it!
