I amPLANNING ON HAVING ONE OF THESE RIFLES BUILT FOR ME SOON. WHAT I WOULD LIKE IS TO HAVE ANYONE WITH ANY ONE OF THESE CHAMBERINGS TO TELL ME THIER INFO AND ON WHAT COBO THEY HAVE ? I TALKED TO DAVE AT PTG AND HE SAID THE ROGUE IS THE ONE TO GO WITH. WITH HIS BORE RIDER REAMER. DOES ANYONE KNOW WHAT THE IDEA BEHIND THIS IS AND HOW IT WORKS? THANKS,
