I picked up a slight ding this fall while hunting out West. I just noticed it the other day. I'm fairly confident it wont really affect the gun's functionality, but it really bugs me.

Any advice on how to gently make this go away? Gun is a Sauer drilling in 16ga and the barrel is full choked.

You need a correct diameter mandrel with a tapered lead in for the size of your barrel. Then tap it in. You may be able to use a wooden broom handle or something similer and easy to shape at home
 
Other than a pro gun smith with the right tool if you could find a ball bearing the exact size of the barrel ,drop it down and bang it out with a Dowel . Or you could have a Swedge machined up and pulled threw . Expanders work but are hard to get them sized spot on . Dont think firing slugs will change any thing or help .no easy answer
 
would do a cerrosafe cast on the muzzle end ,use casting measurements to turn brass plug ,drop plug into barrel and tap in ,put some masking tape over dent as not to mark and using brass hammer work out the dent while adjusting the plug till round again ,if it dented easily it should come out easily
 
I think a tapered pin exerting pressure and tapping with a small hammer of the outside of the dent to draw it out... experiment a little at a time a few times... Don't just drive a tapered pin in hard...
 
Keep in mind that there is choke in the barrel at the muzzle.
I would turn a brass mandrel with a slight taper, and work it into the muzzle, tapping lightly on the barrel, as pmatuk and guntech have suggested. Just work the dented area until it is round, without expanding it at all.
It is remarkable how easily dents can be raised in shotgun barrels. Rounding out this muzzle shouldn't be any different.
 
Thanks for all the suggestions folks. I kinda expected the approach would be similar to what many of you have said. Great info.

Yep with lots of lube so you can get the dam thing back out easily if need be
Cheers
 
I read about a fix to this years ago. IIRC the guy used a piece of 6" long mild steel & turned the end about 001" smaller than bore dia. JUST a bit longer than the damaged section. Then he filed the side of the turned end to match the dent so it would be a slip fit into the muzzle. Now use a wrench to TURN the tool and IRON OUT the dent. Hope I explained it without much confusion?
 
I have had good results with a mild steel or brass rod nearly the barrel size, inserted and tapped against the dented in potion.

With a little care, you get a good result, without the need to have a bunch of exact size spuds to drive in to the various bore sizes and choke diameters.

Brownells used to sell a dent remover for shotgun barrels that was an internal expanding unit that would work too. Dunno if they still sell it.
 
I found an appropriately sized socket. Greased the heck out of it and drove through. Two passes fixed my similar problem. No noticeable effect on choke dimension was observed.
caveat: It was a Baikal IJ12 Russian machine never break down.

Yes, that makes a lot of sense actually. Good approach.
 
Whether you tap in a taper or turn in a taper is of little difference at the end of the barrel... light tapping on the dent is still required while pressure is applied by the tapered plug.

THIS/\

I've taken several dents out of shotgun barrels. Even went so far as to build a hydraulic expander, made out of rolled brass around a heavy hydraulic hose, attached to a small hydraulic jack used for multi tools.

It worked, in one case, to well. Good thing it was a well rusted and damaged practice piece.

You need to be especially careful around side by side or multi barrel combinations. It doesn't take much to separate the barrels.

Another thing you need to be extremely careful with is the edges of the mandrel you make up. ROUND THEM OFF. SHARP EDGES WILL BE ETCHED INTO THE BORE. I've seen this several times.

READ GUNTECH'S words. LIGHT TAPPING is the key. I use a piece of aluminum/titanium as a mandrel/anvil.

You will very likely need three hands to do this job, if you don't have a decent vice, with SOFT JAWS to hold the barrel properly. The barrels should be removed from the action or all sorts of other damage can and will occur. I also use a SMALL BRASS TIPPED HAMMER. It's soft and won't mar the finish. It will however leave some light residue behind, which cleans off easily.

YOUR BIGGEST TOOL will be patience and common sense. OP, your shotgun muzzle is an easy fix, but could go south in a hurry if you get ham fisted.

Got it...thanks to all for the advice. If it goes well, I will post the results. If not, I will hide in shame. LOL
