6GT — New Cartridge, Alpha Brass

[TAJ45]

Interesting Matt. Thanks fo

And a bigger case always shoots faster than a smaller one in the same gun. The 6BR is still slower than a 6GT, regardless of if both barrels 10 or 30 inches.

I would doubt that....doesn't there come a point where short bbl length negates more capacity?
It's short enough where x amount will be burned of the slower powders and excess goes to pyrotechnics and only x pressure can be safely achieved w faster powders....am I wrong? Will listen, no $take in this either way.

Sure, I agree to an extent, but I think that when we're talking about 30gns vs 34gns of powder, you have plenty of powder options in that range to get a full burn. I think that your point might exist a little more clearly between something like a 280 vs a 7 RUM in a short barrel, where you're trying to get 56gns of medium rate powder vs 85gns of much slower powder to burn and not turn the gun into a flame thrower. But I still think the RUM would go faster, just not as much as it would with a longer barrel.

The norma dasher has gone the way of other onscure cartridges like the br rem. I wouldnt chamber one in that these days. It solved a non existent problem about the same time shiraz stopped funding it so it never took off. Lots of people have just had to rechamber since then.

I use Norma Dasher and its working very well at 1K and then I can use the reamer to make the 6BRAI and that is working extremely well. Even if Norma stops making that brass I can form from lots of cases.

I think the Norma Dasher is just like the BRX. There’s a lot more of them out there than the pundits realize. By reading a lot of posts you might think the Lapua based Dasher was it but it just ain’t so..

TAJ45,I have always been a rifleman and always will be with a soft spot for XP-100s,when I went up to Sundance Wyoming many years ago I really was amazed at what this great group of guys and ladies were doing at 1000 yards with pistols.When I was younger the longer and fatter the barrel the more I liked it,but after seeing what can be done with an XP and definitely the right powderI truly was converted.My first time behind Ernie Bishops 6.5-06 XP netted a pd at 555 yards,was also able to shoot a 1.25” 3 shot group at 1000 yards with Dan Meserves 7WSM XP-100.The point of all this is that until I saw what these pistols were capable of I would never have believed it.You are right velocity is definitely slower and they make noise
Ernie even shoots a 338 Lapua improved Some of the guys are going after 2000 yard pd’s with lots of kills beyond 1000+

David Tubb 6xc with small primer Peterson brass. Designed and tested with H4350 and 115 DTACs. No one will touch them for BR.... After shooting them at 1100 yards and was shooting maybe 1/8 MOA (not a joke at all) a 115 DTAC at 3200 FPS I wonder why. I do not play that game I assumed recoil, bu this is so close, I don't see the point.

You an Me both, Urban. Although that diferent/the same game is not without appeal.What if you hit on the one that blyows the BRA out of the water. Specially if it's somethin everbody passed by

 

[6brbb]

It begs the question .... if Lapua tomorrow brought out 6Dasher brass already to go from the box would there be a place for the 6GT. It makes me wonder why Lapua has not done this. Or are there marketing people just that smart?

But indeed if it was named 6GranTorino i would chamber all my rifles in it

 

[blowemup]

6brbb i would also like to see Lapua legitimize the 6 Dasher but the 6GT with a case full of H4350 behind a Berger 108 or Sierra 107 would be worth trying.

I have a 6CMS the brass is 1.970" with a 31 degree shoulder.

Nothing will blow the BRA out if the water. The case is not the limiting factor. Unless it’s beyond 1000 yards or wind is blowing 30mph

Back a few decades, I was a pup having coffee with some older shooters.
One of them said the same thing about the triple deuce.
There always a faster horse in the barn, I tip my hat to those spending their time and money looking.

Lapua won't bring our dasher for the same reason why they haven't bought out PPC brass.

6BR is good as it is and it covers all the bases for guys with BRA, BRX, Dasher, BRV, BRDX, etc. If we didnt have to fireform, we couldnt whinge about fireforming

Well,as long as YOU know, we might as well quit lookin', eh?

 

[22DASHER]

The records already set by the 6 BRA at 600/1000 yards are nearly unfathomable.... I could see a couple of them being beat but NOT blown out of the water.

I stand corrected. There are things tha were written about the 6BRA that would lead to a solution that is not the BRA. It fairly jumped off the page at me and I don't see why no one else got it. Until someone gives it a shot, it's all MT words.

 

[Alex Wheeler]

I wouldnt be looking at the gt to out agg a BRA for Br. The reason we tried the BRA in the first place is to reduce case capacity of the dasher. With the amount of records in such short time with relatively few shooters using the BRA, theres no doubt in my mind it will out agg the larger cases with the 105 class of bullet. I have only chambered one gt in a Br rifle so far, and its shooting quite well with 103s but I think it would shine with a heavier bullet in BR, but there are not many options for heavy 6mms other than factory bullets.

 

[tclaunch]

I can see why it was created, and good job Tommy and George. Should be the cats meow for PRS. The case looks to be begging for RL16.

 

[Alex Wheeler]

Rl16 is what Tommy's been running and it does seem like the perfect match. He still has not had a lot of time with it I don't think. It did win him a relay at the 1K nats with a 3" in LG, so its showing potential.

My featherweight hunting gun got delayed just enough by a wait for one thing that it may just end up a gt instead.
