I've read a lot of articles that define a "Magnum" air rifle as one that shoots pellets at 800 - 1,000 feet per second. Although (FPS) is a by-product of an air guns power it really isn't a measure of energy. I owned an HW90 and I tested more than a dozen .22 caliber pellets when looking for the best performer. They varied from 18 to 21.4 grains and none of them left the barrel at 800 - 1,000 fps. Yes, I could have used a very light weight PBA pellet but most air guns will shoot those between 800 and 1,000 fps. My HW90 shot the .22 caliber, 18.21gr, H&N Baracuda Hunter at 785 fps which is 25 ft/lbs (24.9233), isn't that a "Magnum"? Do you agree that ft/lbs would be a more accurate method of defining a "Magnum" air gun?
