My Savage 10 barrel measures (roughly) .860" at the muzzle (308Win). My Howa's range from .900" to .800". (6.5 and 6mm)
The Ruger RPR measures right around 750ish or so. Both chambered in 6.5CM
I've got another bench like 22 caliber that brags at a full inch.
Again, (IMO, YMMV) for general use, hunting, target, etc. and you're not running long strings out to 1000 yards, that savage with that heavier barrel will do just fine. Honestly,
I wouldn't get too wrapped around the axel on the topic. Not at least until you can without question say you outshot a .850" barrel because it faded in the last 2 shots of a string and had you been behind a 950 barrel then you would have made impacts.
Here is a good read on contours.
