    I apologize in advance if this has been asked before. I recently got into cowboy action shooting, and need to do a chamber job on my SxS so hulls will slide out nicely when I break her open. Any recommended methods?

    Thanks guys.

    I use brake cylinder hones from the local auto parts store. You want to make sure that they'll go down below 3/4".

    If it's a Stoeger, you'll find that the action stiffness is likely not the hinge fit but the extractor shaft sticking in the tunnel in the 'block. Cleaning up the tunnel with a rat tail file will make it open properly and without undo force.

    Brownells sells a really small brake cylinder type hone that fits shotgun chambers. Made by the same company that does the one for automobiles (Lisle). I've never found one that small in auto parts stores or online from anyone but Brownells.

    If you're polishing.....

    Just get a 3.8" dowel,
    Notch/split the end for 2"
    Insert/wrap 320/400/600 wet/oiled sandpaper
    Insert in drill chuck and run at medium speed in/out of chamber.


    Out of curiosity, are you you trying to run ElCheapo steel-base hulls?

    square stone auto hone worked well for my 870 express, and it was bad. If your chamber is just a little rough a ball hone will work too, though I don't think they're any cheaper. I used a lot of oil. Honing took about 30 seconds, scrubbing the slurry out took about 10 minutes. I don't recommend it unless you actually have a problem.

    Don't use cheap steel-based hulls; wood dowel or bore brush with 0000 steel wool and oil chucked in a cordless drill

    I use a 1/4" brass rod, split the end, and wrap emery cloth, usually 400 grit, around the rod till it fits the chamber. Then use a drill or die grinder to polish the chamber. I used this method on a friends Stoeger for SASS competition. With AA hulls, the empties would fall out when the gun was tilted. I always found that a hone would leave a little rougher finish than the emery cloth method. As the abrasive breaks down, it leaves a finer than 400 grit finish.

    Be careful not to make the chambers too big though

    I use a 10 gauge brush with 0000 steel wool wrapped over it, and JB Bore Paste if needed.

    I used the split dowel and sandpaper method on my Stoeger when I was doing SASS. It would then, and still does, drop those cheap WalMart steel based hulls right out.

    I polished the forcing cones on my shot guns using all the abovementioned methods plus using a mop and polishing compounds, with the split dowel you can use different grits paper and get close to a mirror finish. I use a 5 gal bucket with a small coolant pump to pump coolant/lubricant into barrel and let the muzzle return it to the bucket, run the coolant/lubricant thru a filter and good to go again.
