While doing so maybe lengthen it to be able to handle a 2.5 length cartridge overall length. Maybe a Grendel case with the shoulder moved forward just a bit with a bit more taper, possibly 23 degrees to aid functioning. That would make matching the 7.62x51 easy. I actually like the AR15 design myself but if they were to build one just a bit longer and with a larger diameter bolt designed for a .441 case head I think it would be a better overall package. That and 65K psi would make a lot of difference.
Yo Rick:
Want to bet that a cartridge already exists that is similar to the Grendel adaptation you are describing? Or is just as capable with less need to alter basic mechanical things?
I don't know what it is but I bet something exists that has already been proven and is basically what you mentioned.
An extended Grendel case with a more tapered shoulder is no longer a Grendel but something else because now you are talking about a longer receiver. The intent for the Grendel was to function in a standard AR-15 receiver and lower without having to alter the lower or receiver. Sound intent, well executed.
