6mm GT ?

What would be the reason for having so many different calibers?

I have rifles in a lot of cartridges. I keep 2 rifles for match shooting (4 I suppose, if I count my gas guns). I tell myself someday, I’ll build two identical rifles to be used for matches, but every barrel behaves just differently enough, I’d end up with different loads anyway, so keeping different cartridges helps keep ammo matched up with its corresponding rifle.

I’ve enjoyed the 6 Dasher for a long time. It offers better barrel life, lower powder use, and a wider node than 6 creed. So I wanted a 6 Dasher match rifle for a personal bias, let alone these objective advantages. I’ll likely always keep a 6 Dasher rifle, even if it’s not a match rifle.

I bought a factory custom rifle in 6 creed, really like the round, really LOVE the fact I usually have less drop and .2-.3mil less drift than other shooters on the line. I kept the rifle as a 6 creed when rebarreling. The problem is that even with as little as I shoot, I could really go through a barrel and a half each year, or 2 barrels, but have been stretching 1 barrel, and doubting my rifle at the end of the last 2 seasons.

The 6 GT has enough speed and better feeding over the Dasher, AND better barrel life and access to Varget instead of H4350 over the Creedmoor, such it has my attention. I’d leave my 6 creed alone, and rebarrel my Dasher for GT.

So a year from now when I’m rebarreling for the 2021 season, I’ll likely be sitting on a 6 creed and a 6GT instead of a 6 creed and a 6 Dasher for match use, with around 30 other chamberings sitting in my safe for other purposes.
 
What I would be interested to know more about - George comments a GT cleans up a Dasher chamber, and considering I have a spare Dasher barrel waiting in the wings, I was tempted to have the spare reamed out to GT, instead of buying a new one. My smith, however, said he didn’t think it would clean up the throat all of the way, so he wouldn’t go that route.

Not a major hurdle, but something else for me to ponder about the GT.
I was chatting with Tom Jacobs the other day about the GT.
I would be glad to ask a question for you if you want me to.

I’d be interested to hear if George & Tom has actually reamed out any Dashers and how that went.

I looked at the prints and side by sides of the cartridges, and share the same reticence as my smith. I assume both George and my smith are correct - the Dasher neck is long enough to have part of it remain in the GT chamber. So the reamer would just ride that part of the neck, which is often considered a no-no (if it cuts there at all, it’s cutting wrong, and it inevitably WILL cut something as it passes through). Just the very tip of what used to be the neck of the Dasher becomes the very base of the neck above the shoulder junction in the GT. So the shoulder is cleaned, the throat and leade are cleaned, but part of the neck is ridden. It’d work, but a guy has to work harder to ensure it’s done perfectly.
 
I am really liking the look of this for a varmint/play at the range rifle. I have wanted a 6 dasher for a long time for that same purpose but the brass availability has always turned me off.

Yeah, kind of thinking it might be neat to rebarrel my RPR to 6 GT when the time comes. Assuming it has caught on to the point that brass and reamers are free flowing by then.

Starting in 2020, you should see just about the same brass availability for both. I have heard Hornady will produce GT brass, but remain to have seen it, but Alpha is producing both GT and Dasher brass.
 
Honestly kind of torques my crank a bit... I’ve been asking Hornady for Dasher/BR brass for a long time, and I’m sure many others have as well, no idea why they jumped on the GT train so readily? Illustrates how close George is with Hornady, I suppose.

Does Hornady make brass for cartridges that they don’t make commercial ammo for? I can’t think of any

As of right now - yes. Looks like they offer 6 GT brass, but don’t (yet) have a factory ammunition offering. I expect that will change soon enough, naturally.

They actually make brass for quite a few cartridges that they don't load factory ammo for. They are making brass for a ton of older obscure cartridges now like 30-40, 218 bee, 307 win, 303 brit, ect...

I thought of some of the same rounds when he asked, so I looked - They list factory ammo for most of these, and google search does reveal product photos of actual ammo, not just a line item on a website. So they’re making a bunch of obscure brass AND a bunch of obscure ammo.

218 Bee

Well I'll be darned, not only do they have 218 bee ammo but they have ammo listed now for all the rounds I quoted.
