Wondering who out there does true barrel relining. I read up on it about a year ago and found a bunch of places that do low pressure relining where they greatly restrict what calibers you can choose for the project (only very low pressure conversions offered). I did find one place that did normal barrel relining with a website, believe it was in montana, but can't recall the name. Seem to recall it had a reddish background color to the site.
Main reason for the question is in regard to repurposing a rifle with a ruined bore without changing the exterior/original look of the outside of the barrel. For example relining an enfield back to .303, or changing it to a .303-35.
Mainly looking for relining sources but happy to have any other info on the topic. Curious what the minimum barrel wall thickness requirements they have are.
I have heard this was much more common 20-30 years ago than it is now, is that true?
