How does one go about making a Wildcat cartridge?

MM,
I don`t know what the purpous of the rifle is, but if it is going to be an assult rifle I doubt that the extra range you get for the 6.5 bullets will be worth the extra cost. First of all if your building it on an AK or SKS action you will need to have the action worked on to get reasonable accuracy from the gun. Don`t get me wrong, I have 7 different wildcats at present. Acouple I would never built myself but bought after someone else had built and got tired of them. These guns were bought for the price of the actions for the most part and the guy that built them lost a pile of money on them. If you really think you need this rifle go for it, but befor you start the project figure out what it`s going to cost.
