Thread: Drilling out barrel with liner ?

Has anyone ever drilled out a barrel with a liner?

I have a #3 weight original Winchester high wall barrel.
Was .25 WCF and has a .22 liner in it that's totally buggered

I want to still it out and re line in a low pressure bigger bore.
But anticipate it being a bit of a challenge with the liner.
Not sure if i should just drill with my .22 piloted 1/2" long drill
Or try and drill out the liner only first
Or make up a guide that screws on to the barrel threads and heat it all and try and drive out the liner with a punch in a hydraulic press

Uncharted territory for me !

Realistic ideas appreciated, on what might work or if you have ever done something like this ?

Or maybe I'm over thinking it and the piloted drill will just do it all despite the liner ?

Theres a slim chance one of you guys have done this before

Cheers
