I dont know for for sure so I cant speak for certainty but I would venture to guess they are all cut and machined the same.
I have owned a few BACO Model 70's (243, 270 WSM and 2 270 WCF's) in featherweight and sporter configs. They have all shot well.
I also noticed the new addition of these rifles, I plan to get one in .308 as soon as they are available.
