I don't know what "thr indentions" are.

Are we talking about the mag tube dimples?

Yes mag tube demples, i know the drill method but id much rather do the socket method so i don't leave holes in it

Ok. Not sure exactly what size fits, because outer diameter of the deep well sockets can vary from manufacturer to manufacturer.

OK, I was about to send you on a wild goose chase. It's Mossberg that has the cheap tubes. Mossberg has barrel, spring and tube for $150.

Don't be such a tight a$$. Buy a new tube, buy a socket set that will probably pay for itself, or borrow a socket set and don't return it. :D

The tube is brazed to the receiver - I wouldn't smack a socket into it. Unless you want to, A) get it stuck behind what'll be left of the dimples, or B) worse still break the brazing from the shock of hitting it.

Remington supposedly recommend drilling out the dimples. I know guys who use expanding lathe mandrels in conjunction with some other basic components to 'push' the crimps out from inside. Any other method which pushes them out in a controlled manner rather than one which wedges them out with brute force would seem like a better idea. I personally wouldn't drill holes in it like Remington advise, but I'd do that before the socket method.

Give it to a gunsmith who knows what they're doing.

Correct.

But the inside of the tube is around .90", I can't remember exactly without making my way upstairs to check my books.

Edit, ok yeah about .90" - .910".

If you can find something like a drill bit with an outside diameter (od) of 29/32, which is .906. Tap through blunt end first maybe. 23mm is .905.

BTW, I've never tried this, just giving advice on sizes.
