I have been playing with a new Diana Airbug. The postman delivered a package of CARM magazines and one single shot loader so I filled them, put a new CO2 cart in and went out. First the CARM magazines loade much easier than the stock model, and it is definitely more fun shooting more quickly. As for the single shot loader, I think the way it is made I can get off an eight shot string using it as quickly as I can load and shoot a magazine. I had replaced the stock bolt handle with one that is simply a sphere, which I can hook my finger around and operate quicker. The CARM loader flips open, drop a pellet in and flip it closed and run the bolt forward, quick.
