Funny, way back Remington advertised buying a Magnum 1100 and getting a 2 3/4" extra bbl as a "do all" combo.
I think it still a sound concept.

I'd like to find a deal on an LT20 mag, and try some steel dove loads in a standard bbl, see if it'll run. If not, swap in standard sleeve.
Not a big deal IMHO.

If it works, buy a youth stock and let my youngest run it.
