I recently bought a savage 301 single shot shotgun in 410 for squirrel season this year. I believe in comes with a improved cylinder win choke. I have very little experience with shotguns and exactly zero with interchangeable chokes. I am looking for a full choke to install in the gun but nobody can seem to help me. The local gun shop says call Savage. Savage doesn't answer the phone and Brownells couldn't find anything to help me. Is there nobody who makes a 410 winchoke? Is there another choke that's compatible? Thanks in advance.
