I have a favor to ask of someone with Quickload (two, in fact ;D)
1) Could you generate a pressure/distance plot of a 'standard' 7.62x25 load for a 16" barrel?*
2) Could you generate the same plot for a x25 loaded to 223 max pressure of 50ksi?**
3) Bonus points for a third plot of #2 using a slower, magnum pistol powder
*I'm designing a gas-operated 7.62x25 carbine, and it'd be nice to have an estimate of chamber/barrel pressure at the point I'm tapping off gas, as well as an idea of how much energy I'll have to work with at that point.
**I'm playing with the idea of trimming/necking down 223 brass like we'd normally do to make tok brass, only to a .308 inside neck diameter with no reaming, and then loading it to full-on 223 pressures for a sort of "Tokarev Magnum" whose neck will be too fat to fit in a true 7.62x25 chamber.
I appreciate the help, as well as any leads if anyone has heard of this wildcat, before. Also, if anyone happens to know if there would be any shoulder left whatsoever if the 223 case wall were squeezed down to a .308 inside diameter vs. the Tokarev outside diameter. I know it won't be much.
