True but "Only One Pump" though right? A pump "air rifle" can be pumped at least a dozen times for one round. Big difference in the actual force behind the BB.
Not necessarily. The Red Ryder is a spring piston gun. The air is compressed at the moment of firing by a spring loaded piston. Your pump and CO2 guns operate on a different priciple -- gas is precompressed, held in a tank, and released at firing. Not necessarily any difference in power, though given its intended users, the Red Ryder is about as anemic as it comes.
When I started in on the airgun game, the good stuff was the high end piston guns. Now-a-days it seems most of the development is in compressed air. You can design higher power guns with compressed gas, and they aren't as hard on scopes.
I have a Crossman 2100 I keep around for nuisance animanls. I’ve taken out about a half dozen possums up in a tree with it. I aim for their head. IIRC Daisy BB Guns are also spring loads. That is why you only cock it one time. That is what makes them BB guns and not true air rifles. Look on the labels. A pump or C02 will say air rifle. Spring loads will say BB gun.
