1/2x 28 is is the most you will get and still have an appropriate shoulder.This? Also, what size of threads on a Tikka TX3lite barrel. Cut to 20” will 5/8/24 work? Another gun is a Tikka Superlite, fluted barrel, should I re barrel it?
The above isn’t recommended by most smiths for anything over 22 cal.
If you wish to use your barrel buy a thunderbeast and send it to them for a face mount. That’s the only viable solution I have found to the skinny tikka barrel.
You would be near sbr length to even get 9/16th
