I have a buddy who is a plumber and my septic system went out so we did some horse trading. He wanted a 5R Remington he had rebarreled with a Proof carbon fiber barrel and put back in a Christensen stock he had plus do some work on a Christensen rifle he had and I needed to hook up to the city sewer. Last week I built his gun and he helped me with my sewer. He sent me a picture of the first time he shot it. The bottom group is 210 Bergers jammed .015" into the rifling like his 5R barrel liked. The middle group is 215 Bergers .015" off the rifling and loaded hard on the bipod and the top group is the same 215 Berger load but with the bipod loaded soft. The top group is .213". Not bad for the first 9 rounds through the gun.
