DarthMuffin Posted January 10, 2011 Share Posted January 10, 2011 I normally shoot my SLP MK2 with a LM choke in multigun, and I love it. I'm signing up for a match that uses time plus scoring which doesn't reward major PF (which seems to be against the DVC motto, but that's another topic). Since my rifle is an AR10 I was considering shooting heavy metal tactical division, but the only shotgun I have to use is my 20" Mossberg 500 with a cylinder bore. Do you think it'll work well enough to limp me through the match? Do you think I'll be causing myself more frustration than it's worth and I should just shoot my major PF rifle in Tactical and have fun? Link to comment Share on other sites More sharing options...

I saw a lot of frustrated shooters last summer trying to knock plates from a texas star with stock 18 inch cylinder bore 870's and mossbergs at 20 yards. So I would say no get a choke. Some of those guys were even using heavy pheasant loads. The Benelli I was using at the time had no problem with 3 dram 1 ounce shot using a full choke. (over kill but I saw those poor guys not making the steel go down I decided to choke up). Pat Link to comment Share on other sites More sharing options...
MarkCO Posted January 10, 2011 Share Posted January 10, 2011 (edited) There are plenty of folks using cylinder bore shotguns that do just fine. Of course it depends on the match and what the target presentations are. I'd use your "mossy shotty" and have fun. Edited to change "Mossberg" to the correct spelling of "mossy shotty".

MILDOTS Posted January 10, 2011 Share Posted January 10, 2011 In my opinion it is too open for 3-gun at least around here, they like to have heavy plates at distance. Link to comment Share on other sites More sharing options...

AlamoShooter Posted January 10, 2011 Share Posted January 10, 2011 Well the center of the pattern is going to have shot in it. And a good shooter can break 45+ yard trap shots with a cylinder bore. I wouldn't do it , but it can be doable. The Good-guys that host the High Plains event -Proof- each stage with cylinder bore I If the only way I could play was with a 20" cylinder = I would buy some #6 shot and #4 for the longer shots besides what is the cylinder Bore on a Mossy? on a Browning it is .740" a Remy used to be and average of .720-.725 Most Berretas were .730 Each manufacturer will make the cylinder a bit different is size.

Actually this is important, and alot of people don't realize that the bore diameter is different on each shotgun. Link to comment Share on other sites More sharing options...
mpeltier Posted January 10, 2011 Share Posted January 10, 2011 Not only is the bore often different, but the choke size also. This is why it is so important to pattern and/or shoot your shotgun alot. My old remington cylynder bore bbl with out removable chokes and my mossy 500 with cylynder bore non removable chokes patterned very much the same yet had different measurements at the muzzle. My M2 has a. 738 bore size with a cylynder bore choke measuring. 726 and shoots a tighter patterns than the rem or missy did. A wad cup I measured was .715 so I would assume a true cylynder bore (no constriction) could actualy be made in a fairly broad range of sizes and pattern similarly.

DarthMuffin Posted January 10, 2011 Author Share Posted January 10, 2011 Thanks for the input guys. I think I'll just shoot my SLP and and worry about having fun (shooting a .308 with a bunch of poodle shooters has to be good for a laugh, right?). I'm certainly in no danger of winning anyhow.

Regardless of what that tube is marked (Cylinder Bore) your tube is adding .012" of constriction and is going to shoot tighter patterns than a true Cylinder Bore (no choke constriction), more like Improved Cylinder choke in your specific case.

Absolutely right. Thats what I was aluding to. And yes its a factory choke. All the chokes in the five choke set that came with the gun are subsequntly tighter by similar increments. Interestingly a couple of Carlson chokes fall reasonably well within the size they should, as marked, compard to the factory chokes. I have heard that some chokes can be quite a bit off in their constriction. Link to comment Share on other sites More sharing options...

Darth, I ran a Mossy 590A-1 20" Cyl Bore with ghost ring sights at 2010 FB3G. I was able to clean stage 8 except the moving slug target at 50 yds. I hit all the flying clays, even on stage 1. I used Win Universal #7.5 on light stuff and Fiochi high brass #6 on 4 of the poppers on stage 8. Fiochi Low Recoil 7/8 ounce slugs shot very well too. Hope this helps. Now go have some fun.

HardinS Posted September 28, 2015 Share Posted September 28, 2015 I realize this is an old thread. How did the match go? I usually would use my Mossberg 930 JM, but I am competing at the Blue Ridge Mt 3-gun match in Heavy Metal, to be able to do it with a friend in that division. My only suitable pump shotgun is an older Mossberg 590 with a fixed cylinder bore choke. I've agonized over whether this will decimate me or not. I've patterned various loads and tried them against steel plates I have & a popper too. At 30 yards, no birdshot I have could drop my popper, including some HV #4 pheasant loads. Some Federal #4 2 3/4" turkey loads did drop it easily. So I could pay a fortune & run turkey loads - if my shoulder could withstand it. So I've been reading a lot about using CB for 3-gun.

LoganbillJ Posted September 28, 2015 Share Posted September 28, 2015 Why not have your barrel threaded for chokes and have a more versatile shotgun? Link to comment Share on other sites More sharing options...
HardinS Posted September 28, 2015 Share Posted September 28, 2015 Nearest gun smith that can that I'm aware of is about 2 hours away. And I have a race gun I would normally use; don't want to spend much modifying this one just to be able to compete with my friend in HM. Link to comment Share on other sites More sharing options...
Jpat Posted September 29, 2015 Share Posted September 29, 2015 Seen several new shooters struggle with the heavier targets with that set up. Get it threaded for chokes and borrow one for the match until you do. Link to comment Share on other sites More sharing options...

There are dozens of gunsmiths that can install choke tubes in your barrel, and none of them are farther away than your post office. Link to comment Share on other sites More sharing options...
Stlhead Posted September 30, 2015 Share Posted September 30, 2015 Most HM tactical rules allow use of auto loading shotguns, use your SLP. Link to comment Share on other sites More sharing options...
