True wildcat .411 Thornton my fathers doing.
What exactly is it?
Basically it is a 405 win case but 3.25 inch long. He had Bertram in Australia make the brass for him. I have it in a Ruger #1. Pushes a 300 grain Barns a bit over 2700 and a 400 grain Woodliegh right at 2400. The big surprise is recoil is not too bad.
