I recently picked up a Western Arms Long Range Deluxe 12 ga. in excellent shape, 26" barrels.
The bores, which are very good, measure 4 1/4" from the breech, right barrel .752 and left .744; 3" from the muzzle, right .740, left .735. Right muzzle is .711, left .687. The OD 4 1/4" from the breech is .940. Should be interesting to see what it patterns.

From what I have gathered from this thread, my wall thickness is OK; am I correct?

Someone, for what ever reason, had it backbored.

Don't sacrifice the future on the altar of today
