Charles Newton was a very interesting guy. He did develope the 250-3000 Savage as well as the 22 Hi-Power round for Savage. He built a line of rifles that incorporated some interesting design ideas but was never able to really get them off the ground. His first planned mass production rifle was supposed to be the .256 Newton, an early 6.5mm beltless magnum based on the 30-06 basic case. The caliber was decided on in large part because of the easy availability of German 6.5 barrels. Unfortunately, the war got in the way and barrels were no longer available. After the war his financiers turned thier backs on him and he was left high and dry. All of the Newton cartridges surpass thier parent '06 wildcats and a Newton rifle brings a very pretty penny on the collector market.
