I have a brand new, unfired Tikka T3X 20" barrel in 243Win 1:10 twist. This barrel was removed from a new gun as the action is being used for a custom build. Asking $150 plus shipping.
Curious if anyone knows, what if I put this on a Tikka 7mm-08? Would it turn into a .243 immediately, or would the chamber need working? Seems with the two cases being identical, this would be a turn-key swap?
