As I understand it, in time, Richard will offer the AL RBBT in all calibers from 257 on up.
The 300 and 338s are the first being tested. He just started making some prototype 270 AL RBBTs as well recently so that is also very interesting!!!
From talking with him, it sounds like he wants to make from 25 cal up to 50 cal with his AL RBBT design.
