I’ve done a couple savages with x caliber barrels. 6.5 and 6mm creedmoor. I’ve been very impressed with them. The 6.5 is 26” I think savage varmint contour. Bedded it in a Boyd’s pro varmint it shoots stupid good. Once you get the factory barrel off it’s smooth sailing. Good luck!
I think smiths have trouble with heavy hard cast loads such as underwood or buffalo bore. I’ve saw it in one and after some research that was the general consensus
