How short a barrel? Factory choke tubes?
Remington H 70 is a Law Enforcement shotgun, 18 inch barrel without choke. Good Personal Protection gun,
Yes, if it is a modern Remington barrel because these barrels come pre-threaded and accept REM chokes (and many other manufacturer's chokes made for the Remington barrel). Otherwise it will have the choke description stamped on the barrel like, "FULL". I have an older Remington barrel that was a "FULL" choke that I had a gunsmith thread for me. The ability to thread a barrel for chokes will depend on the thickness of the barrel wall. Consult a trained gunsmith.
Have it checked over by a gunsmith first.
Impossible to answer without a DETAILED description of ALL markings, gauge, finish, condition, barrel length, choke, box, accessories, papers.
Go to Remington.com and download an owner's manual. most modern choke tubes have some type of marking that will allow you to determine the choke without removing it from the barrel. some use a notch system while others have stars.
It is possible to fire a shotgun without a choke, but it is highly not reccomended, and they don't cost that much If you select a barrel with no choke (cylinder) it will cause the pattern to be looser than for a barrel of a shotgun that has a tighter choke. The extreme is "full choke" which keeps a tight pattern out to the effective range. Full choke is typically used for waterfowl. A shotgun that is pressed into double duty (shot for small game and slugs for big game) would work well to have modified choke. Slugs have to be designed to fire through a full choke without blowing the barrel but you will certainly shorten the life of the barrel by firing slugs through a choked barrel. If you can afford an extra barrel, then use a cylinder (no choke) for slugs. Remington and other shotgun manufacturers have interchangeable choke tubes (see link) that allow you to screw in the appropriate choke for your quarry.
The short answer is no. I have a Remington Model 1100 Circa ~1963 with a 30" barrel and integral Full choke. This barrel does not accept any additional chokes. You could procure a newer barrel relatively cheaply (roughly $200 new or much less used at a gun show) that will accept screw-in type chokes. Another alternative would be to install an after market screw-in choke system. Not all barrels are candidates, but many are. One such after market installer is "www.choketube.com".
Yes, you can. I have shot countless lead slugs through a full choke, although greater accuracy can be attained by using a modified choke or a non choked barrel.
depending on the condition 100.00 to 250.00.
Yes: A Remington 870 shotgun with a modified choke will shoot any commercial shotgun slug.
A barrel with a full choke.
