Want to build a new rifle on a TL3 action, mostly for steel shooting out to 1k yards. I currently have some 6BR reloading supplies (dies, bushings, and some other things.) If I were starting from scratch I think I would favor the 6GT since I can hit a higher velocity, use H4350 powder (I have a lot), and maybe it feeds more reliably. Seems like the GT should get me an extra 100 to 200 FPS faster than the BR. Thoughts?
Is 6GT worth the "upgrade" from 6BR?

Lots of overlap. It's almost gotten a bit silly. Or it's great. Depends on how one sees it. More choices.
A 6xc can do the same work while coasting and was designed to feed from a mag. Tubb has 6xc brass on sale for $59.

I've had a few people get the 6gt. Seems to shoot fine. I'm not sure it's the wild fire of awesomeness that the buzz would indicate. But it works. These things seem to go in waves of internet buzz.
Do I think a 6gt will outshoot a Dasher or 6bra? No. But I'll wait and see.

IME: The GT has less recoil than the XC.
The GT was also designed to feed from a mag.

At the same velocity, the recoil would basically be the same. I use AR COMP in my 6xc. 34 grains with 108 Berger. That's 2940 FPS and has a very light recoil. Shoots single digit spreads and tiny groups.

I am running a 6GT using H4350 and Berger 108's with a mild load I am at 2,920 fps with single digit ES and SD and has similar recoil to my 6BR with almost 200 fps more velocity.

What is a mild load?

38.1 grains of H4350 and have11 firings with GAP brass and primer pockets are still tight.
Edit: Factory ammo using the Hornady 109 is at the same speed out of two barrels that I have shot.

My 6xc shoots that same velocity with 34 grains of AR COMP.
It takes 39.5 of R16 to hit that same node.
So like I said before there seems to be a lot of overlap
And my Wilson barrels are 26 in Long

Why not shoot the 115 DTAC as it was designed for the 6XC? I have a metric shit ton of H4350 and prefer the case being mostly filled. 34.0 grains in a 6XC case leaves a lot of room.

I think case fill is way over rated. Performance is what matters.
I shoot the Barnes 112 also. Just because the 6xc was designed for the Dtac, doesn't mean it doesn't perform with lots of other bullets.
I have three freebores for 6xc. It does a lot more than shoot 115s. We are testing varmint bullets now.
The true question is how well can you shoot your discipline. If your a benchrest shooter with capabilities like Jack Neary you should shoot what the top shooter do. Same if you want to shoot f class like the top shooters. There's a reason for the caliber and setup. Now if your like myself and shoot 1/2 moa out to 600 and 3/4 at 1k on the best days. the 6gt is for you. I have a home built axis with a criterion 28'' barrel with a Jard trigger. Home built chassis that shoots 105 and 108 bergers with 33 to 34.5 gr of varget to the above standards. All loads exceed 2900fps which will buck the wind better. George and Tom made this with the KISS method in mind. MY2CENTS
Like any other caliber it is all about you and your needs. I like less recoil these days. For perspective my 6.5CM gets fired very little and the .223 gets fired a lot. Yes, lots of overlap and many to choose from. I went with a 6BR for 1000yd work and the .223 works at 600yd. Could just as easily gone to BRA, Dasher, GT, 6x47, 6CM.
"Velocity creep" is tempting. If 2900fps is good then is 3000fps better? Why not 3100fps or 3300fps? Or maybe a 115 bullet is better than a 105 bullet. 6.5 instead of 6. We have so many choices that it can be frustrating to choose.
The good thing is that most of these cartridges can give superb accuracy with a tuned load for your rifle. The other good thing is that barrels are easily replaced these days and can be relatively inexpensive.

@ Charlie, you will LIKE your 6.5 Creedmoor, a Lot more, If you Put a Good Brake on it and USE, 130 grain,..
OTM's, ELD-M's or,.. STGK's ! ( this Bullet weight, works Super, in my 8 Pound, 6-24X Scoped, Tikka t-3X Lite ! )
Group's, in the 3's to 4's w/ 130 gr. ELD-M's and makes, First round Hits, on 8" Dia. Steel Plates @ 850 yds,.. easy !
And Pleasant to, Shoot @ 2,850 fps !
Yup,.. the 107 -108 grainer's @ 2975 fps, in my 10.5 Pound, Braked, 6 XC Do recoil, a Bit Less, for Sure !
I went with a Short action Rem 700 and "Rem-Age" Barrels so that, I could Replace them Cheaply, in my 6 XC.

I probably would, if I could stand the idea of a brake. I just don't like them much. If I had a semi-auto then yes, I'd put one on it for faster follow up shots. But not on a bolt gun. Just a thing I have.
I already load 123's for it, and could add some more weight to the stock, but, at this point I'd rather rebarrel it in something else. I've thought about a PPC for short range (300 and less), but, just not decided.
