The barrel in my Krait Lite Long HP is .222 slugged. I tried a few .22 slugs 217, 218, 219 and all failed of course. I see AVS makes .223 but haven't purchased any yet, and that seems like it would maybe cause some o-ring issues (maybe not) . Does anyone know if someone makes .222? I don't plan on sizing anything. It shoots 25.39's very well even in a un-choked barrel but slugs seem to be what this thing is designed to shoot and I'd sure like to try.
