Swedish 8x63mm Barrels New for Sale
« on: July 09, 2012, 10:26:13 AM »
New Swedish machine gun barrels chambered for 8x63mm swedish military round.  These have been advertized in the SHotgun News as having been threaded for M-98 Mauser actions and are sold as good for 8x57mm rifles.  However, the 8x63mm  cartridge has a larger base diameter (.479")
 than the 8x57mm-30-06  (.473") and if not properly set back will result in  bulged cases. 

Seems like an interesting buy for $89.95, but is there some  costly gunsmithing that would be required to adapt this 8mm barrel to the 8x57 cartridge because of the different dimensions of it and the 8x63mm round?

Here is a web site that is dedicated to study of the 8x63mm round.  It has history, loading data, ballistics, dimensions, etc.   An interesting cartridge for which neither brass nor ammunition is  manufactured.  It's weird, off beat shell casing has a diameter of .479"  which is large enough to cause bulged cases when using brass formed from 30-06 rounds.

The 8x68S sporting round has a base diameter of .511"  and is thus oversized for reforming to the 8x63mm.

They give a 1 1/8th diameter at the barrel shoulder and a 5/8ths long threaded shank. You would in all likelyhood have to cut off the shank, machine a new one and thread for the mauser action for this to work. If this works then you could have a 8mm heavy bbld rifle. Your barrel length then would be closer to roughly 23" OK the bbl is approx 90 bucks, figger in about maybe 150 to remachine the barrel stub and rechamber to 8mm/06. Blueing would cosy about another 200. So all totalled you have close to 400 into the project. Then get the bolt lowered,and d&t for the scope bases or one piece mount.  Find a VZ24 stock that has not been banged around too much and you should be able to open up the existing barrel channel, possibly glass bed the action and first inch or so of the bbl
and mount your optic of choice and then go to the range. So what do we have hear. vz24 stock, swedish 8mm/06
chamber,and just in case you were contemplating an action vz24 action providing you  can find one in decent shape. Buy a rem 700 in 30-06 remove the existing barrel and have a commercial 8mm tube fitted and chambered for the 8mm/06 cartridge. For use with at least 200 grain bullets. Or fit the bbl to one of the BSA Martini cadet or better yet 12/15 action with thicker sidewalls. But what about the chamber for cast bullets you could use the 357mag necked down to 8mm. Might actually be a good cartridge. Frank



to 8mm/06. If I had the tools and someone standing over my shoulder. I'd take a whack at it. Should be able to equal
