Have you slugged those bores or are you depending upon the net for your measurements?
Yes, in fact I slug all of my bores since I shoot a lot of cast bullets.
My 1911 rifle is 310" across the grooves.
K31-s are tighter and usually have .298-299" bores and .3075" grooves, all of mine uniformily have this dimension.
Also if you have a Swede 1896 or 38 with a bore diameter of .266, you've got a very worn bore. The rifles were never manufactured with bores that large
.
You are correct, Swedish mausers were never made with .266"
bore diameters, is one did have a
bore diameter of .266, it would most definately be worn to a smooth bore. Luckily, rifles don't wear out that way, they wear out from throat erosion and muzzle wear.
Swedish Mausers- I have 8 of them, I haven't slugged the 'new' Husqvarna that I recently bought, but the rest of them are .265-266" across the grooves. My M41B is .266" across the grooves and will easily shoot 3/4" 5 shot groups with140gr SMKs(cast loads are a different story
), if its worn out, I'd love to see what one of these would do with a new barrel
Sprinfields- I have a 03A3 that is luckily to me closer to .308 in the grooves (.3085") but its also a 2-groove.
