You will not have to worry about dies if you don't want to, Tactical Ammunition will produce commercially loaded ammunition for the 6x68.

If I understood the above posts you have to size in two steps with two different bushings? It may be considered a biased opinion( so take it with a grain of salt) but personally just paying a little more and being able to size in one step and getting a a bump in performance seems to be a no brainer.
You are correct. I had to dig back a ways, but here are the two uppers I started with. One is a 1:10, the other a 1:12. I had been chambering barrels and building the WOA for a couple of years, so wanted to give the simple neck-down a try. I was disappointed with what I was getting out of the chamber, so after talking with some very knowledgeable folks, got a reamer ground with the sharper shoulder and slightly greater case-capacity.
I had the unusual opportunity to do some “real comparison” where I actually used the SAME barrel, before and after. I don’t know whether it was the sharper shoulder, or the little extra case-capacity I achieved, but the increase was worth it in my opinion. Hindsight being as good as it is, I sure wished I would have done the DTI in the first place.

What were the before and after numbers?

There is nothing wrong with the 6x6.8. I got enough better results with the improved chamber that both my first customer and myself decided it was worth the change.
For the first year or so, I kept the 6x6.8 reamer and offered a chambering choice to my customers. They could choose between the simple neck-down and less expensive dies, or the improved version and custom dies. Not one single one of them opted for the simple neck-down, so that option simply faded away.

I am with you on the pissing contests, I quit reading posts about caliber choice as soon as a 6.5 or a 6.8 guy whips it out.
I do not see a pissing contest starting here, clearly you design has more powder capacity, and is faster, that is just a fact and can not be disputed.
You have a uniquely rare apples to apples real world test with the same barrel, I would love to know the results, if you do not want to post it publicly, please PM me, and it will not be repeated.
Thanks, Paul
