Often enough, factory CYL bore barrels have just a few points of choke in them, to help even out patterns. And for the past several years, Remington's factory 18- 20" barrels have been mostly choked ImpCyl. Those usually work very well for buckshot or rifled slugs.
Chopping off a longer barrel is going to leave you with absolutely no choke, unless you get it fitted for choke tubes (another $70 or more) or try 'jug' choking it. I always recommend that people who want shorter barrels for HD get a factory short barrel rather than cutting down a long barrel.
Shop around- I still see deals on Remington 870 barrels, I bought a 20" CYL bore barrel (with a 3-shot Remington factory magazine extension included) recently for $125, delivered. It showed up in the Buy/Sell/Trade section of another board.
