If I do anything with the 6.8 SPC cartridge in 6mm, I will probably make up one with a 30 degree shoulder angle, a bit longer body, and with less body taper to increase the case capacity and put some more "horsepower" behind it. This could be done so you could just run the 6.8 SPC cases through a sizing die to neck them down and set them up to shoot in the chamber, and you could use these pre-fire formed loads for practice, offhand, and sitting. This set up would also allow a guy to rechamber an existing 6mm/6.8 SPC to the "improved" version to get the extra "horsepower" and velocity.

Robert,
I very much like your outlook on the "horsepower" side of the 6mm/6.8 SPC variant. I was looking for something similar 30-32 degree angle shoulders and lessening the body taper to obtain additional internal capacity. After all, my main intention was a space gun based mid range,300-600 yd)rifle exclusively.
But then, Holliger's iteration was the only available platform that fulfilled my criteria at the time,almost a year waiting). Without forgetting of course that he specifically intended this to be an across the course cartridge. That it has showed amazing performance at 600 yds is a big plus.
Also, John has volunteered that we could experiment with a more potent and dedicated mid range variant of the 6mm WOA.
Nonetheless, although the thought has stolen some night sleep away from me, reality occasionaly finds the better part of my brain and reminds me that if "horsepower" is what I want, maybe I should remain with the dedicated bolt action, faster caliber rifles standing in my safe. BTW, I bit the bullet and got hold of a Hendrick's 6CM last summer. Only had time to shoot it twice. It is scaringly fast and accurate. It will be my long-range rifle for many years to come, specially if the barrels last as long as he says.
Bottom line, I guess it's Chevy and Fords like you said.... lol
