[potatoe]

Ohh, I got a10 twist in the works I'll be posting soon to. . . Good luck

I use H414 in my 14 twist 6-250 with 68 gr match bullets at 3650fps and my brass lasts forever. It’s a tight neck chamber and I can push it a LOT faster if I want to make new brass more often. I thought the only purpose of a 6XC was to shoot the high BC bullets?

There is less case capacity than a 6 creed and more than a 6gt. Is my reason for doing it.

Good brass, accuracy and good speed

It was developed for them but reloaders will find a new purpose for pretty much any cartridge especially varmint hunters lol

One of the most impressive barrels I make is the 6br 30 FB 12 twist. As far as just shooting small, it is hard to beat. I betcha my 6xc 50 FB with my 12 twist would blow the doors off. Shoot a 70 TNT probably about 3800 FPS easily.

My 6-250's were fussy about what they liked. Took some messing with to make them shoot the way I wanted. Still have1 and it's very nicely accurate with it's particular load - and super good custom bullet - , but not yet been on the chrono. For me the purpose of a 6XC was the reported outstanding accuracy, and really good very tough brass with 6-250AI capacity. If this thing works as I believe it will, that 12 twist 6-250 could become a 6XC......never know.

I'd be surprised if you weren't pretty impressed with a 12tw 6xc. I really liked the one I had, 70-85gr bullets were fun for woodchucks, crows, and coyotes. I ultimately settled on a 10tw for the 6xc for hunting though.
The 6xc using light bullets has been long overlooked as most of the press has been on LR shooting with them. Just my experience with them, but I've been happier with the button barrels than cut rifled barrels. They just seem to shoot more accurately right out of the gate and maintain their accuracy for me. FWIW. WD

My 24" Hart,14 twist, chambered with a .030 freebore reamer:
65g V max-3800 fps
70g TNT-3740 fps
76g Norma Tip Strike-accuracy node at 3690 fps, tiny, tiny groups
AA2230 with Federal 210 proving the most accurate, and they were not the max load. The above are at the accuracy nodes with groups in the 2's in a Remington Varmint stock, hogged out to accept the light-weight contour barrel, Jewel trigger, 10-60 Sightron

60g Sierra and 55g Nosler ballistic tips are next

I have tried 4 different powders with the 70g tnt, and the AA2230 proved to be the fastest with incredible accuracy.

These velocities stomp the results that I got with a 14 Twist, 6 Dasher, and the XC was not all that picky between the powders... user-friendly compared to the Dasher.

18" 8 twist from @urbanrifleman has been installed. Will be loading up 70gr TNT up to 105gr soon. Will probably throw my day scope on it for bullet testing.

That is a sick rifle.

Some initial work with my Hart 14 Twist with .030 freebore-24"

60g Sierra, Rem 9 1/2
39.0g of AA2230-3870 fps
39.5g -3919
40.0g -3950
40.5g -3978-No pressure on this load, primer still round

55g Nosler Varm, Rem 9 1/2, AA2230
39.0g-3967
39.5g-3979
40.0g-4053
40.5g-4089
41.0g-4096-No pressure on this load

55g Nosler ballistic tip, is more accurate shooting in the 2s at 41.0g at 4096 fps, but I spend little to no time in a load tune, and AA2230 was the only powder I worked with.

These beat 243 Win loads in speed in barrel lengths the same length.

Two friends here are killing a lot of deer with the 70g Nosler ballistic tip...who in the world would have thought of that combo?

In my 8 twist, 87g through 108 shot extremely well, but with the .160 Freebore I put in the chamber, 70s did not shoot tiny groups, but good enough to kill a coyote with. In the 8 Twist, I would start with an 87g bullet at the lightest, but an 80g Berger may work very well, if you can find any.

Years ago, I killed a lot of coyotes with the 60g Sierra in a 243 Win and 6 Rem when I was hunting in Mexico, one heck of a bullet. Also, the 80g Sierra Blitz is a superb coyote bullet, and you hear the extremely loud PLOP sound every time you hit one!

In this particular 24" Hart, 14T, .030 freebore, the 70g tnt and Nosler ballistic tips are shooting in the very low 2's at 3740 fps, this is one heck of a coyote load, and with a few of the 75g Hornady V max, it was super accurate at 3690 fps, not playing with but one powder, AA2230.

A 26" barrel, 14-12 twist, .030-.050 Freebore would be pushing the 70s at or close to 3800 at the accuracy node. Speed kills.

Faster twist, more freebore may bleed off some speed, but you do not know till you try, Best Wishes!

Tubbs Brass is incredible in how tough it is, even with the large primer pockets.

Dave Aflac made some videos of shooting rock chucks with the 75g V max with a muzzle velocity of 3800, shot out of a 6 Rem AI. The chucks were launched 15 YARDS in some cases. The 6 XC with a Long barrel would be in that neighborhood, and a 29" 12 Twist with 75 Grain V max would make a very, very impressive chuck/p. dog rifle that would equal my 243 AI in performance with a LOT less powder.
