[William Watt]

I had the 6x47 based off the 222 mag case.
Very accurate cartridge, low recoil.
In todays world the 6BR would be a much better choice.
Enjoy

CFE 223, varget for heavier
80 or 85 grain cup and core kills deer dead.

Absolutely, I’m already shooting the 6ppc as my benchrest rifle and a other 6ppc for varmint! Tried the H335 & N133 but im not satisfied yet, On my way to try it out with the H322, will see..

Of course!! How about the BLC2? Twist and length of your barrel?

I had an autoloader in 6x45, so I was limited in bullet selection based on OAL, also limited even further by a 14 twist barrel. I didn't have enough time to start load development before it was banned. Was going to be a fun little project.

I own both. The 6x47 is more accurate with appropriate bullet weights. I have the parts here to put a 6x45 together, but haven't got around to it yet. - dan

I picked up a single shot Cooper chambered in 6x45 ..... absolutely love it !! It is ridiculously easy to convert 223 brass to 6x45, simply run it through a 6mm expander ball. I have had very good results loading 80 grain bullets with N130. Very economical to load however I am still getting close to 2800fps. I plan to work up a load with Barnes TTSX which more than enough energy and penetration for deer and antelope at sensible ranges.

Yes It's a simple caliber to load and it reach really good precision with bullets in the 80's to 70's

I had good results with 748 in mine. - dan

This is a cartridge I have been intrigued by given the ease of converting .223 brass. If barrels were more readily available I would own one. I may have to buy a bolt gun in 6mm ARC instead to scratch the itch.

 

[oppy]

I've had good results with IMR-8208 XBR, with projectiles in the 75 ~ 85gr range.

 

[struff55]

i have used 8208 xbr with 55-85 gr bullets with benchrest accuracy
i also use the same powder in the 223 with excellent results i like the fact one powder for the two cartridges
i also have a 6x47 2// mag case and a 222 rem i like small cases
