Guys I have been thinking.

Would it be possible to build a .577 TYRANNOSAUR or even a .700 BMG IMPROVED on a 50 BMG action???. I think it will be big enough.

Let me be the first to caution against doing any type of thinking in the future.

Here is the relevant law:

78-27-51. Inherent Risks of Thinking.

The Legislature finds that the act of thinking is inherently risky and may cause injury to self and others. Therefore, the Legislature hereby establishes as a matter of law that certain risks are inherent in the act of thinking, and that, as a matter of public policy, no person engaged in the act of thinking shall recover damages from another for any injury or loss which is directly or indirectly occasioned by such thinking.

Amen!

Overkill- Now you have an even bigger problem. You have to figure out how to bush the bolt face down, to fit the Nyati or T-Rex rim,. You also have to figure out how to get one to extract. You could get Mcmillan to make a Bolt specifically for the T-Rex or Nyati, but then you'd still have a single shot. The magazine actions are too large for either cartridge. A custom single shot Maadi- Griffin shell holder action could be built for these cartridges, but the cost would be pretty high. You are talking the same price as a BBK02, custom Enfield, Granite Mountain etc.-Rob
