I've shot a Kadet kit a few times, and I gotta say, it's a pretty sweet pistol. As for ammo, I usually go with the 38 or 40-grain stuff that's moving around 1150-1250 FPS. But that's just me, you know? Suppose you're looking for reliable .22LR ammo for your Kadet kit. In that case, try out a few different types and see what works best for you. It's all about finding what your gun likes. Oh, and have you ever tried
32 20 wcf ammo? That stuff is legit. But I need to find out if it's compatible with the Kadet kit. Anyways, good luck with your search for the perfect ammo.
