12g magazine tube - Slighty ovaled - how to return it to round

[Fez]

Hi folks,
My Mossberg 500 magazine tube is very slightly 'ovaled' and so the follower hangs up when trying to feed the last 2-3 rounds.
Does anyone have any suggestions on how to bring it back to round?

Thanks in advance!

Force a metal cone down the inside I guess.

Or replace it.

I have one I'm not going to send back if you want to talk.

Vice, and force it back

Buy a new one through Brownell's. They are not expensive.

If you have a rod that is a slip fit inside the tube you can drive it through to iron out the tube, but you will never return it to perfectly round.

Anybody that rebuilds/restores Shotgun can probably fix that . It a expanding tool I seen used, that they slide down barrels and true to take dents out .

I'd definitely prefer to keep the money in the NWF family where possible. Do you have a dent tool or an extra magazine tube?

No, I do not.

Can you buy a wood dowel in the proper diameter and run it though the magazine tube? Not sure myself.

 

[Fez]

Thanks for the help everyone!
I'm always in favor of investing in tools, but $90 for one I'd likely only use once won't work.
Brownells is out of stock for the mag tube, but I'll check some online sites too.

The one on ebay seems promising.

My experience with trying to make something roundish again with a vice/tools has always failed.

I looked into things I could drive down the tube, like a socket, but nothing I have fits correctly. I've considered buying a ball bearing that might do it but I'm not sure if it would do the trick. I figure I'm also likely to get it in and not get it back out.

Lazyfaire might have a solution.

I made this to fix those pesky bent tube openings. They get bent pretty easily when the cap is off.
I also have a hydraulic dent raiser for sliding down inside the barrels or mag tubes.

Nice! I'm out in Kennewick, WA but my folks live in Salem and they're about due for a visit. Whereabouts are you?

[v0lcom13sn0w]

i tried lots of things and ended up spending the $15(back then) on a new one

Smash your ammo so it matches the tube?

Armor piercing round!

I've used a ball bearing that fit the diameter. A bit of oil to lubricate and a wood dowel to press the bearing on through.
Started at the good end.
