Newton parts are hard to come by and the major firearms gun sites are the best places to monitor for any for sale. I have not done too much reloading for Newtons and hopefully the guy who I rely on for info will stop by and enlighten you. My listed favorite loads for the 256 (a First Model 1916) are 53.6 grains of RL22 with a 120 grain Nosler Ballistic tip or a 125 grain Nosler Partition. I have tried to use 140 grain bullets with average sucess. The rifling in the 1916 is suited to the lighter bullets and the Second Model 1924 has rifling more suited to the 140 grain bullets.
