Is this a simple neck down, shortened or improved or anything... what's the story?
This is a simple neck down. I am using Redding full length bushing dies in 6.8 SPII. It takes two bushings, a .285 and a .268. For a seating die any Hornady 6mm or 243 6X45 will work. I am using Silver State Armory brass.
I plan on trying out the first prototype barrel this week end. I will post my results.

First day at the range with the 6X6.8 was unbelievable. I was shooting 3 shots and clean. Breaking in was a breeze. I never did get any copper. This thing is going to be a winner for sure. I was only shooting 3 shot groups, and trying to do a little load work up. I was getting 1/2 inch groups. a few were even smaller.
I was shooting IMR 8208 with a Hornady 58 gr. Vmax and getting 3350 FPS and that is out of an 18" barrel!!! This could be the ultimate truck gun " short and fast" I can't wait to shoot the 22" barrel that Andy has in the works.
I have some rounds loaded with Benchmark powder. I will post the results after I get back to the range. Next time I will be taking my camera with me so I can get some pictures of my rifle as well as some targets.
and you can see what he managed without even half trying. My working with the 6X45 from BHW lately is showing me some super velocities with the 87's at 2970 and per barrel length I think this one will be even better as the case capacity is increses a nice amount. I PREDICT that a guy can get 3100 to 3150 out of a 24" without an issue and with judicious work 3200 might be reached.
The major factor to remember is barrel length enters into the equation. Guys want to run a shorty 16" tube and then want to get velocities equivalent to one that is 20". It can't be done SAFELY. Also remember that the test barrel that Ritch has is ONLY 18" so he is slow from the get go. I will get a 24" tube at some point depending on what I get to start with but this one will be a great round for varmints and even some target work if I am not mistaken.
The cartridge was designed for 87-90 grain bullets as a max though it may well handle some a tad heavier but then you are giving up case capacity and speed. I think a 90 grain Nosler Partition would be a good deer round and the 58 VMAX will be one coyote whacking machine and any other PD;s that pop up to take a look!
The best firearm for self defense? Any loaded one will do.
