I recently purchased a stoeger m2000. I read on one of the forums, of folks having problems with their chokes sticking & deforming. I have had no problems with my chokes. I will be using this gun for waterfowling,shooting steel loads though it. I was wondering if I should be concerned about the reports. I use the mod. choke for steel. I also wonder if any one had experience with these chokes,they are more constricted and claim to hold tighter patterns for longer range with steel. Any thoughts
