    Improved cylinder vs modified choke? I want one for self defense. What is the differences in chokes out a 14'' barrel. Plan to use 3inch and 2/34 magnum 000,00,0 no1-4 buck shot, slugs, etc. Maybe will shoot bird shot sometimes. Whats the best for a tight pattern? How far can I accuretly use one of these 14'' barrels?

    There is no realistic tactical reason to use 3" or magnum loads for defense, particularly in shorter tubes. Personally I like my fighting shotguns with open cylinder, particularly if I'm going to be shooting slugs.

    Whats the difference between patterns these? Can you shoot slugs in the tighter chokes?

    You could always have the barrel threaded for Accu-chokes, then you could experiment and put whatever you wanted in.

    Patterns will vary a lot on a number of factors, not just the choke. You can shoot slugs through some chokes, some it is not such a good idea. I personally wouldn't want to shoot a slug through a modified choke unless it was an emergency.

    Just out of curiosity, why all this concern about patterns and such if going with the 14" tube?

    I don't know if there is such a thing as a tight pattern out of a barrel that short. I'd get her drilled out for tubes and see which one it likes. Full, maybe?

    A 14"? Cylinder bore.

    you don't really want to discuss 14" barrels with game wardens. tedious and embarassing.

    Haha. The game wardens here would probably ask if they could take a few shots. I could legally hunt with a fully-loaded 590, or a AK with a drum mag. :-D

    Even with the 14" barrel you wont get much spread within self defense distance. I see no need to use a choke. The 14" barrel improves the maneuverability of the weapon so unless you live in a large mansion with huge rooms you should be fine using 2 3/4" #4 buck out of your cylinder bore barrel.

    Slugs go through a modified choke just fine, except for very hard (and obscure) slugs like a Dixie.

    SOME slugs go through SOME modified chokes just fine. SOME don't.

    Hence the second part of my statement. Any Foster or Brenneke type slugs found at Walmart, Dick's, Big 5, or the local gun shop will safely pass through anything but the tightest extra full chokes. You really have to look for the type of slugs that absolutely require an open choke.

    They will usually pass through. How safely they will do so is up for grabs. I've seen way too many gun/choke/slug combos fail to recommend anything beyond IC.

    First, I agree with a previous poster that 2 3/4" full-power Buckshot shells are sufficient for defense, and kick way less.

    Second, as long as slugs are not going to be used, I've found through actual field testing that FULL CHOKE always gives the tightest pattern with both buckshot and birdshot.

    If slugs are anticipated, CYLINDER BORE is necessary to keep the choke from being battered. Luckily,full-power Federal Tactical 9 pellet OO Buckshot (with their special wad control) patterns almost as well out of a cylinder bore as out of a full choke. (This is by far the best patterning OOB load I've ever tested!)

    If you are going to have a screw-in choke installed, it doesn't cost much more to get all 3 sizes and field test them yourself (IC, M, F.).

    Lastly, I've found (if all else is equal) that bigger size buckshot always patterns tighter than smaller sizes. Tightest patterns (that I've actually tested) in descending order are OOO, OO, 4.

    As for effective range, it varies with the loads. For example, my CYLINDER BORE 18" with the special full-power Federal OOB load mentioned above will keep 1/2 the load on an IPSC target at 50 yards. But........with other brands my CYLINDER BORE is only that effective out to 20-30 yards.

    On the other hand, with my FULL-CHOKE 18" 12ga, I can do almost as well at 50y with Winchester SuperX 2 3/4" OOOB. That combo will usually keep 1/2 the load on targert at that range, and penetrates deepest.

    Bottom line: Shotguns take a lot of experimenting to determine exactly what each will do with what load. For sure I would use only OO & OOO Buck. In my testing, I found #4 buck spreads too fast and doesn't penetrate as well. :supergrin:

    What 14" barrel has ever been made with a choke? All I have ever fired were cylinder bore.

    :cool:

    Ahhhhhhhhhhhh, you've led a deprived life! Screw-in chokes can be installed in any length shotgun barrel by a gunsmith.

    I should also add that now that I live part of the year in an RV park where 100's of thin-sided RV's are parked 15' apart, I load my shotgun differently. Because of the obvious danger to innoceents, I now load three #3 size birdshot shells, followed by 2 OOB. In no other cases do I do this, but here I have to consider the neighbors and thin walls!

    True, a good gunsmith can INSTALL a choke.

    What 14" barrel comes from the factory with a choke set up?

    :cool:
