In the BR world, the 6x47 was the round that dethroned the 222, and the 6PPC dethroned the 6x47. If I recall the 6x47 was a 222 Rem mag necked up to 6mm. Once the 6PPC came along, the 6x47 all but vanished over night. Sierra loading manuals still have the data.
What Can A 223 Be Rebareled To/Rechambered For?

Actually the 6X47 never really dethroned the 222,it was developed by Mike Walker of Remington fame , to use in benchrest sporter class ( must be 6mm or larger ). It wouldn't shoot with the 222 ,it was tempermental and erratic.
When the PPC came out it was first shot as a 22PPC and that case dethroned the 222. Then that developed into the 6 PPC and the rest is history.
I shot a 6X47 for a couple of years ,then when the PPC caught on I changed and never looked back.

Indeed. It is a 222 Remington magnum necked up to 6mm and it perfect for 65-80 grain 6mm bullets. googling 6-x47(old) yielded lots of results. The 204 Ruger is a 222RM necked-down. I have run my 6mm expander mandrel in 204 brass and it works just fine.
Redding has the dies, and they are available anywhere Redding match dies are sold. It likes H322, H335 and BL-C2 powders.
I checked and Hodgdon has all the reloading data on-line as well.
There is absolutely no question the 6PPC is the ultimate inherently accurate short range BR cartridge, but it isn't a 223 bolt face. The 6X47 is a classy round that has been eclipsed by bigger better things, but it is still a neat littel cartridge with excellent accuracy and barrel life.
I suspect that if it were set up to use light bullets, it would nake a very good varmint gun too.
I am planning on building one myself.

Woulda had more interesting options.
I have a 6x47 (the original, not the Lapua version). Good round, accurate as hell out to 300 meters. Would probably work real well further if you had the right twist. I have load data at home for it. It used to be a relatively common wildcat. - dan

After pondering some stuff I kinda got thinking again about the 6X47.
Looked at Berger's web site and saw a good range of bullets for target shooting. From 62 grainers right up to 105 or 115....
So what barrel twist would be a good idea? My interests are more into long range target shooting. So heavier bullets would be more desirable.

8" twist or faster for the heavier bullets ranging in the 95 to 107 grain for long range work, you might be able to get away with a 9" twist for the 95-107 gr's, but certianly not for the heavier 115gr DTAC. I think David Tubb used a 6 or a 6.5 twist in his 6XC and the 115 DTAC bullets.

9-10 twist would let you use up to 90 grains, although I think this is top of the scale weight-wise. Don't waste time thinking 105-115 bullets will be good. No way. Throat would need to be cut to take them and this cartridge is not designed for 115 grain bullets AT ALL
90 Lapua and Berger offerings are outstandingly accurate, and can even achieve good 500-600M results. personally,I's stick with 65-68 grains...

It was designed around 300 yard BR competition, but I've seen a couple of coyote and ultra lightweight deer guns built in this cartridge. A standard 1-9 or 10 twist will stabilize bullets up to 100 gr or so. With a 1-8 twist you can go heavier, but keep in mind that you velocities from a case with this capacity will not be high. On the other hand, you can push the 85 gr X bullets at good speed and that will kill anything up to deer sized game. - dan

After allot of humming and hawing, I'm gonna trade the Browning or sell it.
Did some nosing around about changing barrels on a Browning and makes me nervous with some of the potential outcomes.
