Not much traffic on this round lately. Is the cartridge good as Mr. Tubbs says?

It is designed to not wear out barrels as quickly as the 243Win did on across the course rifles.

For NRA Hipower or prairie dogs, it's a great round. Barrel life is nearly half again as good as the 243Win, and you don't give up too much at 600 yards and its much softer shooting on the short course.

I am currently shooting a 1 in 14 twist. 70 grain bullets from the 21.5 inch barrel do 3500 ft/sec easily with great accuracy. Case life has been superior. Those I have seen shooting heavy bullets were extremely accurate.

I figured you'd get a little more speed than that? What is the case capacity of the XC? 3500 is nothing to sneeze at but I can push 70 grain bullets to 3100 out of a 20" 6X47 Rem 1:12 twist barrel pretty easily.

I didn't even look at the XC when I built my new .243 1:7 twist for 115 grain DTAC and Berger. I decided to "KISS" since I had a ton of .243 components. The only thing I considered besides the .243 was the AI version and even got a RCBS .243 AI neck die bought, but in the end I stuck with the plain old .243 Win.

However, when David Tubbs endorses something it is hard not to look at it.

I was thinking the same & he has a fine record with the cartridge. I want something accurate & a little easier on barrels than the 243. I tend to shoot the same thing over & over so like my '06 the rifle will see much use. Also want no feeding problems.

Likely a caliber that should be investigated.

I just read a short piece on this cartridge last night in the African Hunter Magazine.

What does it say?

It said it is a further advancement of the 6mm BR. It says the case is longer and the powder has better burning characteristics because of its shape. Also, said it is more stable in windy conditions because of the higher velocity. Finally, stated Norma is offering three loads, 95 gr Ballistic Tip, 100 gr Oryx, and 105 gr Berger.

I actually have gotten over 3600 ft/secs, but acceptable accuracy wasn't there, and the brass life at 3500 ft/secs is now on it's tenth loading and the pockets are holding strong. Note as well this is a 21.5" barrel with a 14 twist, so greater speeds and heavier bullets would need a different approach. Case capacity is supposed to be about 7 grains less than a 243 Winchester.

I understand that and 3500 is still a good usable velocity in my book. I played with several powders and primers to get 3100 fps out of my 6X47. Settled on 26.5 grains H335 and CCI 450 primer, that nets me about 3/4 MOA with NBT. I got much better groups with the Sierra 70 grain BK but I've been buying Nosler blems and have a pretty good stockpile. I think for the 70-80 grain bullets the little X47 case has it going on and it feeds from a magazine wonderfully.

That's pretty good velocity considering barrel length but you are shooting 1/14 twist barrel.

Years ago I build the 6x250 with 1/14 twist barrel but 24" long barrel using 35gr powder high 3400fps. I could of pushed it to 3500fps back then.

I later moved up to the 6x250AI.

You don't see lot of the F-Class being used IBS/NBRSA like the 6XC.

Different game completely. The 6XC was designed by Tubb to be a good across-the-course NRA Hi-Power round. It's optimum for 200-600 yard target shots, good for deer to 400 yards and great on prairie dogs to 800 yards.

It's not a 6.5x284, or a 243AI.

I know no one using 6XC for deer or varmints. I do know that Tubbs has changed the design of his case over the years till he finally came up with the 6XC.

Rifle has shown itself to be a consistent .5 moa performer, and occasionally a little better. This was the first attempt at distance with it, going with a lower node and greater case life.

Well, I got the barrel as a take off and the dies and 90+ pieces of brass came with it. I knew going in it was a "wrong" twist for some, but I have so many light 6mm bullets it made sense in this component short environment.

21.5 inch Shilen match, 1 in 14 fluted. A good friend fitted it for free, and away I went.

I doubt you'll find any ammunition for the .243 at Walmart suitable for 1000 yard shooting of any kind.

May travel 1 to 1.5 miles....

If you launch it at 37.5 degrees and there is no head wind it will go that far before hitting the ground again. If you launch it level with the ground and the ground is fairly flat it will hit the ground (from 5 feet off the ground) at around 230 yards.


Speer, Sierra, Lyman, Hornady, Hodgdon have reliable reloading data. You won't find it on so and so's web page.
