Clark--

Thank you kindly for your warm welcome. You can see that I am not on this Board very often. Usually, I'm on the trail of more guns and rifles for Westley Richards Agency.

The 700/.577 was a collaborative effort some years ago amongst our client, Westley Richards, and Wolfgang Romey who loads our metallic ammunition in Germany and was intended to be a one-off effort.

I am not familiar with the origins of the T-Rex but I think our 700/.577 cartridge predates it.

Sorry for the tardy response.
