I was curious if anyone has tried this. I know it is going to require custom dies. But, my feeling is that it would be a nice little cartridge to drive 140s I am guessing 2900-2960 fps in a 30-32" barrel. Right now, getting around 2850fps in a 26" barrel is typical in a standard 6.5 creedmoor. I would throat it out a bit since it is a long neck and you can seat that bullet out a ways already. Adding the improved shoulder would get me case capacity. Visualizing the cartridge, it would truly look like a big brother dasher.
The other option is to keep the shoulder the same, but throat the chamber really long. In my current tactical setup, I am seating a 140 hybrid to aboyt 2.86" OAL so I can mag feed. it looks like I could seat the bullet out quite a ways in the neck and maybe that might allow me to get to 2950fps.
Any comments on doing this?
