Goody, SASS #26190 1,120 Posted December 5, 2010 Have it threaded for screw chokes. Then you can change them at the drop of a hat, or as often as you change your mind. Choke tubes are around 18-20 each. I shoot all my CAS guns with an open choke, also known as cylinder bore. Some like to have a little choke, so maybe Skeet or Improved. I think modified or tighter would be a bad idea in CAS. Share this post Link to post Share on other sites
Smithy 0 Posted December 5, 2010 I read an interesting thing in another thread about the 97 and its choke. Apparently their choke has a long taper to it so if you know the choke you want and have a good smith doing the work, he can cut and measure bit at a time to get into the tapered section at just the right point to give you the choke you want. If the barrel has already been cut and removed, then choke tubes are your only option. Smithy. Share this post Link to post Share on other sites
Driftwood Johnson, SASS #38283 1,033 Posted December 5, 2010 Howdy I have used everything from full choke to cylinder bore. It doesn't really make much difference. Although I had some trouble knocking down a distant target with cylinder bore the other day, a full choked gun might have been some help. But for targets up close, you should be able to put plenty of shot on any target with any choke. Share this post Link to post Share on other sites
Guest diablo slim shootist Posted December 5, 2010 you may not need a choke we will pattern it after we cut it and you may not see a lot of difference at close range- how often do you shoot at clay birds anyway-not often and i still hit with mine easily.

Shotgun Bandit 0 Posted December 5, 2010 All my gunz have choke tubes. In my opinion it gives ya a better pattern(less flyers)...90%of the time I use I/C but I have Mod & Full in the cart iffin I need em for a stubborn target............Bandit Share this post Link to post Share on other sites
Texas John Ringo, SASS #10138 58 Posted December 5, 2010 Thanks, Shameless Talk to Pecos Red, he can fix you up. He has the tools and the know how and I'm sure you can get in touch with him easily, he does belong to the same club as you Share this post Link to post Share on other sites
Dubious Don #56333 183 Posted December 5, 2010 You install choke tubes. The tooling is around 400 bucks and the proceedure is pretty straightforward. It can be done on a lathe or by hand. The interior of the barrel back from the muzzle is reamed out to the diameter of the tube. The threads are cut with a different tool and you're done! Screw in the choke tube and go shoot. Oh, I forgot to mention you need to make sure there's enough barrel thickness, do this to a thin barrel and when you shoot it the muzzle comes apart like a flower. (sort of pretty but useless) If you use side pressure when reaming, you can actually cant the installation and then your shot ain't gonna go where the sights are pointing! If you run the threading tap too deep into the barrel, you'll screw up the ledge at the back end of the tube and raise a nice little ring that will be darned near impossible to get out. If you don't use enough/proper cutting oil, the tool will chatter. This makes for interesting new cuss words! If you screw up the threads while cutting them (easy to do) not even JB weld will make things work and the ONLY solution is whack off a couple inches of barrel and try again. (if you have enough barrel) Share this post Link to post Share on other sites
Madd Mike #8595 2 Posted December 5, 2010 mic the barrell 97's can have thin spots hence after threading????? super this spot I got me one, that is less then paper thin on ne side of the choke Share this post Link to post Share on other sites
Rio Brazos Kid 38 Posted December 5, 2010 I have to agree with Shotgun Bandit. A little choke is much better than none. Yeah, you can get by with a Cyl. Bore, but it leaves a lot to be desired. Having patterned several guns and various chokes, I.C. (.010) seems to be the better choice for our game of CAS. It helps keep the pattern together for those close knockdowns, and still is open enough for the occasional Clay Target that is sometimes thrown. RBK Share this post Link to post Share on other sites
BLACKFOOT SASS #11947 424 Posted December 5, 2010 How? You get a handfull of twenties and go to a good gunsmith. Is it worthwhile? Opinions will vary. Blackfoot Share this post Link to post Share on other sites
Daybreaker 0 Posted December 5, 2010 I had 2 97's that were spreading shot from Florida to Texas. I carried my shotguns to Trulock chokes in Whigham, Georgia. One was Open Cylinder bore and the other one was More than that. With that being said these were both Norinco 97's. Had Jared thread the barrels and I bought a sack full of Chokes. It is amazing how good this works! http://www.trulockchokes.com/cgi-bin/eShop/index.cgi Share this post Link to post Share on other sites
