i know a couple guys shooting the 140s and like them they just never shot up to my expectations...the 108ELDs i shot 30 of them and that was enough.
the only bullets ive shot the will shoot better than bergers are the 105g infinitys but at $253 bucks a box ill stick to the bergers.
you want easy to load and stupid consistent get yourself a 100 108g bergers and load them .025 off and run a charge test and ill bet around 2950 and 3050 youll buy more...smallest groups ive ever shot at distance were 108g bergers.
108 Bergers are super accurate. Great bullet

Figure I'd pass on some info. Just talked to Steve at X-Caliber since they're running 30% sitewide today.

If you call and get your order in, you can lock in BF/CM prices and then call them back with your order number and have them tag it for 6GT chambering.

They are still waiting on reamers and will have to confirm specs and make test barrels before production. Figure 10-16 weeks based on what I gathered.

Snagged a 26" 1:7.7 m40 profile to jump into the 6mm works.

Has anybody bothered to work up some RL16 loads with either the 105s or 112/115s? I know StaBall has everybody hot and bothered since we can meter it but I'm real fond the temp-resistance in RL16 for shooting throughout the year here in OK

The new batch of 112's I can't get to shoot. Shot the 112 all last year and loved them. New batch are no good. Back to Berger's. Wanting on the 109's
How new a batch are you talking? I just got 1000 rounds in from MidwayUSA last week. Loaded up some rounds with 33.2-34.0gr Varget and 38.2-39.0gr of Staball 6.5. Hoping it's an easy load development and I didn't waste my time/money.

Barnes sold out of the 112 last year. Production started again in August. I got 15,000 in last month for friends and me. Had them shooting ok at 100 yards. Tried about 200 rounds with. Varget, h4350, and staball 6.5. H4350 was the best. Shot a local match and had funny groups going at distance. Came home an shot these groups at 200 yards with the match loads. That's a 1 inch dot.

I need more.... waiting on my AI AT Pre-Fit from GAP in the 🌈🐅. Is it basically gospel that the 105 Berger is the most reliable bullet out there? Seems like when every one else's are inconsistent that one just works, even with a bit lower bc.

if i had to choose only one bullet id take a 108g berger over the 105 hybrid and i shoot a lot of both.

Anyone know who has savage prefit barrels in 6gt in stock or quick turn around?

Anyone ran these out of MDT 12 rnd mags? Any issues with feeding or loading? Im having a hell of a time with my 6.5x47L jamming in them due to their internal ridges sitting right on the shoulder. Wondering if the 6GT has the same issue being a similar size. Im looking to go that route, and making sure each round is seated perfectly (not too far back, not too far forward) to ensure the mag works is a huge pita.

X-caliber, this morning, posted on FB that they are now doing prefits. AR barrels are still in testing.
Just some added info, I spoke with Steve at X-caliber on Cybermonday (before 6mm GT was live on the site) and it sounded like 10+ weeks. I ordered to lock in that sweet 30% discount and then called to have it tagged for 6mm GT. Steve mentioned they were still waiting on reamers and would have to cut test barrels to measure for spec and then they'd start producing for customers.

Ummm....I'd hold off on them.... they seem to be unable to deliver barrels right now.

However PVA has agreed to a group buy of 6GTs.... They need 10 for a group.
Not trying to be snarky but PVA has had serious issues with timelines and delivering barrels.

What's up with straight jacket? And what makes you think PVA would deliver in any reasonable time frame when they are backlogged like crazy already?

Honestly asking, not trying to start something.

Are all of 419 pre fit barrels shouldered? It looks that way based on description. As far as 7 vs 7.5 twist rate, will the 7.5 be better at stabilizing heavier bullets?

Here's what I know. I've been waiting for a barrel from straight jacket for 5 months. From their Fathers Day sale. I've been told twice that a barrel was cut and then told that they didn't actually have the contour in stock, twice. I changed my order to a contour in stock and then told they lost my order. I changed my chambering and caliber even to accommodate something they had in stock. I was told that their headspace guages were bad. I was told the guy that supposedly modified my sales order didn't actually update anything. Finally, after many apologies I was told they were going to cut the barrel Monday and ship it Tuesday. It is now Wednesday.

PVA was stating Dec 31 delivery times or money returned on their BF sale. I'm not saying PVA is through their troubles but I'm just saying Id hold off on SJ. Notice they didn't run a BF sale...

I was told 7.5 is what most of the shooters are using and that is what I ordered. Plan on shooting 110 A-Tips onceI work up a load but am burning through a box of 105 Hybrids to get the barrel settled in. First barrel I’ve ever gotten from 419 but so far out of the gate it’s a shooter!

If you shoot at locations that commonly have a negative air density and plan to use the troubled 110 SMK , you may want to consider a 7 twist. I shoot 115 Dtac's and 112 Barnes and both have been stable at -500' DA and I am using a Impact/Bartlien 7.5 twist currently.
Berger has a stability calculator on their website that can be very helpful if your concerned.

@reubenski that is discouraging about Straight Jacket Armory. I have an order in with them that is at 6 weeks and 2days. They confirmed the blank was in-stock before I ordered... and tried to up sale me into a 5 day turn around for $100 more. I'll give them till next week before I check in since their website clearly states a 6 week turn around.

So, from here and FB, it looks like most are getting dasher speeds with 2 more grains of varget.

Is anyone seeing 3050-3100 with a 105 hybrid and no pressure?

I have a GT reamer, but seeing everyone running at dasher speed is making me reconsider.

I’m already setup for dasher and have no issues feeding in my AI with mag kits.

You must not question the new shiny.. new is ALWAYS BETTER! :)

I agree with your assessment... The appeal of this cartridge to me is running H4350 class powder at 2950 fps with a 109-115 class bullet. I can do that with a dasher and varget, but that's leaning on it pretty hard.

Straight 6br didn't run reliably in my AI AT, even with a mag kit so I'm going to give this GT a try.

If I can run H4350 with a bullet between 105-115 grains and get Dasher/BRX speeds I'll be happy. I'm just glad I will be able to use the same mag for my 308, 6.5 CM and 6GT. I'm going to try out the 105 Berger for reliability but I have had good luck with 110 Sierra's and 115 DTACS in both a 243 barrel and 6BR so I might work up loads with all those since I have them on hand. I have plenty of Varget too but it supposedly torches throats quicker than H4350.

Would love to use the 110 A-Tips but I'm cheap in an expensive sport and 75 cents per bullet is hard to swallow.

I’ve seen a few in the FB group I’m in get those numbers with the 105 Hybrid.

I believe the purpose of this cartridge was to get the same velocities as the other 6mm’s with less pressure so more barrel life. Have seen a few guys comment that they’re over 2K rounds on the barrel and still running strong.

For shooters like myself that had already planned on switching to a 6mm this year, the GT is intriguing for the barrel life alone. This is my first 6mm so nothing to lose.

On the sixth day, God created the 6mm. On the seventh he rested at his bench. Thus the 6mm bench rest was named.

Over the decades evil came into man's heart and corrupted God's creation and there was no end to the grumbling of man, that his new stick wouldn't eat reliably, that it's life was short lived at 70,000psi.

God saw this and sent his Son into the world, not to condemn the world but to bring forth his new creation. Those who follow him in the light will have everlasting barrel life while feeding unimpeded.

Those who choose to walk with him in the light will also be granted matching speed without fear of pressure.

You may be struck down and I may get a boil on my ass for laughing but your sacrilege is funny. Next time work in George Gardner, with the beard it shouldn't be too hard.

"For he did shew forth his hand in might, and brought to the children of men the gay tiger, that they might have everlasting barrel life, and mags that floweth over with not-too-stubby cases...and the Lord did grin."
