When Dr. Marsh decided to build actions, he got Gary Ocock to assemble one with a modified Bruno stock and a Krieger 13.5 twist barrel. At the time I was writing for Precision Shooting Magazine and he sent it to me for testing. From the start, it was one of the most accurate rifles in 6 PPC that I have shot. Below is pictured three consecutive 3-shot groups shot with 3 different N133 powder charges and Berger 64.2 gr Column bullets.
