This is an interesting subject...
I am considering a liner for a repro High Wall.
I remembered a post by another gunsmith not too long ago which I found and copied below.... As there have been a confusing number of 32 caliber cartridge's developed over the years and their varied dimensions and twist rates I thought I would "copy and paste" it below for anyone considering a 32 liner.
In my case I want to stay in the similar bullet length / weight / diameter
for my liner as my other 'Rifle' 32's
I have a 32-40 with a 12 twist., a CPA 32-20 that shoots 200 grainer's well, so for me a .322 Groove with a fast twist is where I want to go.
Spoke with Bob Hoyt today. His leade time is "Next Spring"
"TJ's has three 32 cal liners, 32-20 with .312" groove 1-16", 32-40 with .323" groove1-16 and 32 Special with .321" groove 1-14"." ==========================================

As you may have seen in another thread, my 32-40 is down at the moment. I just got off the phone with Bobby Hoyt and we talked for a bit about different calibers and his suggestion is to reline back to 32-40 since I'm all set up for the caliber already.
I have no experience with relined barrels, so I'm curious if anyone is using them with good results in schutzen, and also if anyone has used his liners? He will make up a liner, install and rechamber for cheaper than just a TJ's, so curious if anyone has results.
I'll likely have him re do a 45-70 to 40-65 in the future too
