So I have searched all over for the best way to remove those pesky dents that Remington adds to their shell tubes. There seems to be two methods:

1. Drill the tabs out, dremel it, wire brush it, and add your tube extension.

2. Buy a $75.00, "tool" that you insert in the tube to expand the tabs out.

Honestly, neither solution is even close. If I drill them out, I now have two dam holes in my tube where all kinds of crap can accumulate causing a shell jam. If I buy a tool to do it, I have a $75.00 piece of metal that I probably won't use again. If I do that, I'm the tool to be honest..

I saw a suggestion where someone took a 4 to 5" socket, coated it with gun oil, and gently tapped it into the tube to push the dents out. I am going to try this. Does anyone else have a suggestion?
 
I want to say I used a socket on an extension and worked them out a little at a time.

They can be removed with a little elbow grease and thought with basic hand tools
 
Once the big socket is by the dimples and then doesn't want to come back out, load the tube from the chamber-side with small diameter sockets until you can see them and then whack them back out.
 
I dont have my 870 handy, but are not the dimples hidden under the barrel/magtube band ?
I did mine the hardway. round file, filed until they where gone. It left holes but I did not care. The miny drum sanders on a dremel tool would have made short order of it.
 
That worked great. I used a 7mm socket coated with gun oil. Also coated the inside of the tube. Banged it in there with a hammer and then used a socket wrench to twist it out. There were still some shards of metal left over, so I used a cylindrical metal file to get rid of the rest.

Now to figure out how to get this dam light mount to fit when the tube extension is larger than the barrel [rolleyes]

Tested it at the range today and didn't have any failures. This method works just fine.

Would a gun smith be willing to do this? I'd like to add a mag extension but I am not the most "detail oriented" person......I would probably ruin the tube.
 
I believe I tried drilling out the bumps, but it wasn't real satisfactory, the shells or plunger tended to catch on the edges from time to time.
