Just got done putting a new barrel on my Eliseo R5 Tube Gun. It's built off of a Rem 700 action. I acquired it and am the 3rd owner. No good records were kept of round count and I have never been happy with how it groups (This should be an easy 1/2" or less gun and I never did better than 3/4"). We bore scoped it and it looked like a chainsaw massacre in there! Off it comes: no confidence in it.
It was a Broughton 6mmBR 7.3 twist.
New barrel: Pac Nor 6mm blank, 8 twist.
Here is the basic pile of parts and a close up of the action glued into the tube.

First step is chuck up the barrel, insert correct sized pins, and center it up based on the centerline of the bore, NOT the outside diameter of the barrel.

Next step, shave off the breech end square, then pare back the area where the threads will be to the shoulder.

I didn't get a pic of cutting back the breech face to accomodate the bolt face (Remington's "3 Rings of Steel"), but after that, hog out the majority of the chamber with an appropriately sized drill bit, then rough chamber it with the reamer (6BR with a "no turn" neck of .272).

Will have to continue this in a reply because of pic limits………..
