I have only comissioned 2 custom rifle to be built for my own use as i usually built my own. The first of the 2 was a 7x57 that was built by my friend and classmate Clayton Nelson. I picked the 7x57 because in over 55years of building rifles I had never owned a 7x57. After completion I took it to Africa as my plains game rifle. It was built to use 175 Gr Noslers Partitions and that is what it shoots best. 3 shot groups average well under 1" but due to rather light barrel start to climb as the barrel heats up. The rifle weighs 7 lbs even and is a pleasure to both carry and shoot. I took several Kudu and Impala on that safari with ease and would consider it to be adequate for any plains game in Africa as well as some dangerous game. With it and my 416 Rigby I feel perfectly armed to take anything offered. The 7x57 has easily become one of if not my most favored rifle.
