Just thinking about a cartridge...

[DaveMachine]

So I was playing around with a czech m43 round and I noticed the extremely small shoulder on the catridge. Has anyone ever made a wildcat using a 6.5 bullet and the 7.62x39 case?

Would something like this be feasible?
Would it improve performance significantly?
Would it be too expensive to build the cartridge?

Give me your thoughts.

6PPC is basically a 6mm improved version, and is one of the most accurate cartridges ever used. 6PPC originated from the .220 Russian, which is a 7.62x39 derivative.
A 6.5 version could be made. There would be the cost of a special order reamer and custom dies.
