I have two of them, a three-digit 1st Model Newton and a Husqvarna 9000 (S&W C) that Ray Montgomery in Grand Junction rebarreled for me. It is my favorite long action 6.5mm bore cartridge, certainly a winner that never took off due mainly to being introduced at the start of WW1. First Model Newton barrels are identical to 1903 Springfields, so a 1st Model Newton barrel can easily be screwed into a 1903 Springfield receiver and a 1903 Springfield barrel can just as easily be screwed into a 1st Model Newton receiver. The 256 Newton is sort of a long action 6.5 Creedmoor.
