The new Crosman 760 Pumpmaster pellet/BB gun features a pellet magazine. I had a 760 about 35 years ago when I was a kid and you had to load pellets one at a time. Now there is a 5 pellet magazine that slides into the action. It’s pretty slick.
Anyhow…the Crosman 760 Pumpmaster is a huge bargain at around $30. It’s powerful and accurate. You can buy one here….Crosman 760 Pumpmaster Pellet/BB Gun at Amazon.com
Here’s an interesting review on the Crosman 760. You can see how the pellet magazine works.
