NOT short, light

Yes, lengthening the forcing cones or lengthening the chamber,
BUT I will leave it as is. I have MANY shotguns and a round of skeet with a 65mm chambered full and fuller choked gun will keep me humble and make me keep my head down.
If I need a light kicker on a particular day I will use the Remington 1100 with factory cutts comp. Very little recoil there.
And I rarely use a 12 gauge for hunting anymore, unless Sandhill Crane or Geese.
Or may fit some Briley 28 gauge or 410 bore tubes or ????
Have some extras somewhere.
Hope to weigh the gun tomorrow
Mike
