I’m about to buy an FAC pre-charged rifle and I remember reading an article that you wrote some time ago in which you gave the ideal power settings. From memory, it was 900 speed and 40 pounds, but I’m not sure. Can you tell me what it should be and why, please? By the way, the reason I cannot go back to the article is that I give my back copies of Air Gunner to an old chap who lives near me because even though he doesn’t shoot any more, he still enjoys reading all about it. It’s a wonderful magazine and I look forward to its arrival every month. JOHN
Hello John Thank you for the kind words; they mean a lot to us. My ‘magic on-ticket recipe’ is a 16 grain .22 Air Arms Diablo Field pellet flying at 900fps which means just under 30 ft.lbs. muzzle energy. Over many years, I’ve experimented with every calibre I could find, from .177 to .30, at whatever muzzle energy the manufacturers could offer, even up to 100 ft.lbs.. I’ve never seen a pellet fly faster than this and remain accurate. Many people have told me stories about rifles that could exceed this speed with total precision but nobody has ever put one in my hands, so at the moment I consider 900fps our upper velocity limit. You could choose to shoot the heavy .22 Bisley Magnum at that speed and get around 40 ft.lbs., but I see no advantage. Any rabbit, squirrel or pigeon getting in the way of 30 ft.lbs. will be very impressed and another 10 ft.lbs. won’t impress it any more. Further, to attain that extra energy uses an exponentially increased amount of air from your reservoir, which significantly reduces the number of shots per fill. Running at this power, you also begin to notice the recoil a little more and although it’s still very small, it does make the rifle marginally more difficult to shoot accurately. Lastly, I believe that if you need more than 30 ft.lbs you should buy a .22 rimfire. They’re cheap, light, convenient and deliver around 100 ft.lbs. silently for no effort at all. The question is do you need all that power? I don’t, and I’m perfectly happy with my airgun’s performance. Ed.
After much testing this is what I believe to be the ultimate FAC set-up
