I recently inherited a Winchester Model 12 (12 guage) shotgun. Does not look like it has been shot in over 40 years, and actually has cobb webs in it. Anyways, The barrel has one of those old Lyman Cutts compensators on it, I looked the part number up and it appears to be a extra full choke. Not nessiaslry what I want for skeet shooting. From the research I have compiled it appears that these chokes do not come off once installed onto the gun. So my question is, can I take the choke off so just the adapter is at the end? And what type of spread will this give me? The choke system comes as a two part system, it has this funky little muzzle brake that the interchangeable chokes are screwed/unscrewed onto. The only choke I have in my possesion is the extra full choke, which brings me to my next question...Where can I get a cylinder choke, or at least an IC choke? I have seen a cutts spreader choke, but have no idea what it is, is it the same as having no choke at all? You may have gotten a little lost so I will sum up my three main questions here. 1. Can the shotgun be shot with no choke installed, but the lyman adapter still on, just nothing screwed in? 2. Where can I purchase a skeet shooting choke for this adapter? 3. What is a spreader choke, and does it give a similar spread to a cylinder choke or IC choke? Thank You!
