Bought a used gun and the IM choke is stuck in the barrel. I’ve shot steel shot through IM chokes before but I noticed CZ doesn’t recommend it. Anyone use it for goose or duck hunting? In case the choke is cross threaded I don’t want to try to get it out until after February goose season since my normal gun is waiting on a part and is unusable. Trying to get through a 4 day hunt is why I bought a CZ 712 first generation.
