I just need to find a powder that works. Either going to be Vihtavuori or Reload Swiss over here, slim pickings recently. RS62 might work.That's where I run my match rifles 35.6-36.0 H4350 with 115s 2820-2850.
The top node for 105-112gr bullets is from 2950-2900 depending on bullet weight/powder. My 24" tube will run these velocities not too far from pressure, 0.7gr, which is bout 50fps, which is what you'll lose cutting 2" off, minimum. This would make things pretty spicey. I'd run a 6cm at 20-22". No problems running the creed mid 2900s with a 20" barrel. My 22" shoots really well at 3080 with 109 eldm/ rl26.What’s the brain trust’s opinion on a short barrel GT? Thinking 20-22 running 109s or smaller.
Reality is I’ll never have time for comps so a 26inch comp tube makes no sense. Mainly a plinker to 1000 but also short range (under 500) whitetail and pigs.

Yeah you would. Personally if she's already shooting 6cm(and you're not tooled to load 6gt), I'd just spin up another creed. There is ammo everywhere, quality brass from several vendors. Every one I've had, has shot very well, but so does a gt. You'll likely be happy with either choice, and soubd set on the gt. I personally just really like the 6cm when it comes to hunting. I've also got a 6saum, and smith is waiting on my barrel to cut a 6prc.So let me throw this out there.
I have a 6cm (wife’s), 260 243 and several 25s. Getting rid of the 243 barrel for the GT and the gun will be run suppressed. We box stand hunt here in TX and a 24inch barrel with suppressor can turn into a circus depending on blind size lol. I’d be fine running in the 2800s. Based on data I’d be good to 500ish for my AO.
That’s part of the reason I’m set on the GT is I have everything for it, brass dies bullets etc except a barrel. My 25creed is a hammer with 135s but it’s big and bulky. I may go 22inches and call it good lolYeah you would. Personally if she's already shooting 6cm(and you're not tooled to load 6gt), I'd just spin up another creed.

I'm no brain trust but, I built a 20 inch GT because I already have all the stuff for it. I have a match barrel but I rarely shoot bolt action PRS stuff anymore. Love the cartridge so I gave it a whirl. Last time out my load of 33.4 gr Varget gave these results. This was rounds 100-110 out of the new barrel. I think in the next 100 rounds or so it should settle in right around 2800fps with a berger 109lrht.What’s the brain trust’s opinion on a short barrel GT? Thinking 20-22 running 109s or smaller.

That's awesome info thanks! How do you like the setup?I'm no brain trust but, I built a 20 inch GT because I already have all the stuff for it.

That's moving right along! I just ran 107smk though the womans 26" 7.5tw Hawkhill 237 bore barrel, 33.4 and they were going 2860. Has bout 160 rounds on it. This exact load did 2950 in her prior 7tw Hawkhill. Less twist, 50k longer freebore, and lower round count must be a lot the difference. I ran same exact load of 35.8hr H4350 w/ 115 dtacs in my 30, 28" 26" barreled rifles one day, there was only 50fps between all three. These were all Alpha 170fb hawkhill 7.5tw 237 bores from same batch of steel. So not quite apples to apples, but close.I'm no brain trust but, I built a 20 inch GT because I already have all the stuff for it.

That’s my exact load I run with my DTACS out of a 26.75” barrel.I ran same exact load of 35.8hr H4350 w/ 115 dtacs
As a point of reference, I have a 22" GT gas gun (GAP Bartlein) and get 2850 fps with 107 SMK and 6.5 Staball. 20-22" in a bolt gun would be plenty for deer, hogs and targets out to 1k.What’s the brain trust’s opinion on a short barrel GT? Thinking 20-22 running 109s or smaller.

I forgot to mention I have 2000 CCI 450 primers.@Malum Prohibitum
I'd use the 105VLD's to get a 100 or so through the barrel to get it up to speed or close and get your brass fire formed 31ish grains .020ish off the lands.
Then either bullet 106 or 107 your choice...again at .020 off the lands start at 31.5g and work up .3g at a time...CCI450 is my preferred primer.
I am shooting 108g Bergers .020 off, hornady brass, CCI450 and 32.8g Varget 24" barrel at 2800fps
no i don't ?Any ideas on where to find some brass headstamped "Gay Tiger"?
Pretty sure GA Precision is the only ones who get that from Alpha. At least thats the only place I've saw it in stock. Other vendors may get it too, idk.Any ideas on where to find some brass headstamped "Gay Tiger"?
Case fill will be low, I'd try H4831sc, SW4350 or N555 at 2700-2750. But if that's where I wanted to run speed wise, I'd go straight 6br.On Hodgdon load data. 34.3gr of H4350 will be at 2700.
The PPC funnel is what your looking for... https://www.dillonprecision.com/s000233 13085 is the number.Anyone know the correct Dillon Precision powder funnel insert for the 6GT? I don’t see one listed in their chart and don’t know of any other common 6mm with a 35 degree shoulder (closest might be an ‘I’ insert for the 6mm Rem?).
I load on a 550 press and manually drop the charges from Autotrickler V3 into an Area419 funnel but this requires a proper insert to fit the case (or one very close) thanks for your help.
This is from a brand new 20" Carbon Six barrel. 7.5 twist.What’s the brain trust’s opinion on a short barrel GT? Thinking 20-22 running 109s or smaller.

Nice. Just ordered a barrel and will be cutting to 20 probably. so looks like 2900 will possibly be doable.This is from a brand new 20" Carbon Six barrel. 7.5 twist.
That is going about / almost as fast as Hornady Match in 6 GT was out of my 26 inch Bartlein barrel.This is from a brand new 20" Carbon Six barrel. 7.5 twist.
33.5 of H4350 in a 26” had me to 2750ish It was happier at 33.9 and basically 2800flatAnyone running 109 hybrids at 2700-2750? What powder and charge?
Can someone get me the max case length for the GT, can't find that shit anywhere..
i can't help you sorryI just need to find a powder that works. Either going to be Vihtavuori or Reload Swiss over here, slim pickings recently. RS62 might work.View attachment 8462297
The point of the GT is to shoot the heavies faster, if you're not doing that then a smaller capacity case makes sense.I would like to run Berger 105 and ELDM 109 out of a suppressed 22in barrel slow at around 2750 with H4350. I’m thinking 34g of H4350 would be gtg but worry about not efficiently filling the gt case. Should I do a 6gt or step down to Dasher of BR?
Or shoot dasher or BR speeds in a standard AICS MAG without having to experiment with spacer kits and various mags.The point of the GT is to shoot the heavies faster, if you're not doing that then a smaller capacity case makes sense.
Your plan will work but I might take a little more H4350 with a 22” barrel to make that speed.I would like to run Berger 105 and ELDM 109 out of a suppressed 22in barrel slow at around 2750 with H4350.

You think so? My guess of 34g might be off then, I just want to run them nice and slow. Will get new MDT mags for either BR/Dasher or GT anyway. I had a 26in 6GT before and I didn't like the length with a suppressor or how the ARC and MDT AICS mags didn't run 100% for me.Your plan will work but I might take a little more H4350 with a 22” barrel to make that speed.
Bergers lists a case fill of 104% of H4350 with 109g hybrids at 36.3g. Obviously there is variation in cases but I think you will be fine at anything between 34-35g. 35g would be 100.4% and 34g is 97.4% according to Berger. So even if you dip to 95% then you are still good to go.I think I might be up to 35g of H4350 to get 2750fps out of the 22in barrel. I'm just worry about low case fill as @4O6shootist mentioned above.
I needed 35.5 gr H4350 in my last 26” GT barrel to get a 109 Hybrid to 2860. Subtract 100 fps for the 4” shorter barrel and you are where you want to be.I think I might be up to 35g of H4350 to get 2750fps out of the 22in barrel. I'm just worry about low case fill as @4O6shootist mentioned above.

Yes, it's backward I found H4350 to be super temp-insensitive for me here in SoTex and I have a crap ton of it. Are you at 100% case fill at 35.5g?I needed 35.5 gr H4350 in my last 26” GT barrel to get a 109 Hybrid to 2860. Subtract 100 fps for the 4” shorter barrel and you are where you want to be.
Your plan will work but I’d never choose a caliber around a powder. That way of thinking seems backwards to me.
FYI- Accurate AICS mags have been 100% reliable for me. MDT, not so much.
I’m in north tex and found the same. Over a 25 degree difference from 100 to 75 my speeds were only 13.4fps lower.Yes, it's backward I found H4350 to be super temp-sensitive for me here in SoTex and I have a crap ton of it. Are you at 100% case fill at 35.5g?
