View Full Version : 20 ga. choke on a 12 ga.?

my grandpa recently gave me a winchester model 370 12 ga full choke but it has a sleeve on the end that enables you to put a 20 ga. choke on the end.
he was big int spot shoots in his day would this help?
have you seen or herd of this?
good idea or bad?

WOW! That sounds pretty scary putting all that 12 gauge powder and shot thru a 20 gauge choke.:eek: Something dont sound right with that setup.

Does that sleeve really use a 20 gauge choke on a 12 gauge barrel? I have GREAT difficulty believing such a thing is safe or practical. Sounds more like a device to allow fitting a tighter/extra full choke. Some people erroneously think/thought that 20 ga guns shoot smaller patterns than 12 ga guns and could thus call an extra tight 12 ga choke a "20 ga" choke.

Could you possibly have misunderstood? They do make shims for the chamber where you can fire a 20 gauge out of a 12....:o

Almost sounds like someone is looking at an old Lyman choke. Some of the old choke tubes were marked with te amount of constriction, so if it were marked 20 it would mean a constriction of .020". A 20 gauge bore diameter is about .110" smaller than a 12 gauge.

I was wondering the same thing as hogdogs. A chamber insert to fire smaller shells?
