Hi guys, Last Feb. I bought a 112v single shot in 243 from Bob White. I told him I wanted to make a 6br out of it. He sold me a used Kerger barrel that was 6ppc. he did all the fitting and I had him bed the factory stock. I started working loads using Hornaday 58g V-max, Lapua brass, cci400 primers and varget powder. Yesterday was the last fine tune of the powder charge. using 33.2g I got a one hole 3shot group at 100 yards. I went home and took a loose bullet and it has just a little space around it. Minus the bullet size I get .052...I didnt test bullet seating yet and I dont know if I will...If you need a benchrest rifile give Bob a call at Shooters corner in New Jersey, he is a great guy to deal with and does very nice work..
