I am interested in hunting with the 350 Hornady roundnose. I have worked up a load with 54 grains H322 cci 200 primer and winchester brass. As I do not own a chrony I was hoping someone could tell me the approximate muzzle vel. and trajectory out of my 18.5 inch 45/70 guide gun. Also any comments on the effectiveness of these bullets on game ranging from deer to moose would be helpful. I live in Alberta, Canada and I can encounter just about any game on a typical weekend hunting trip. Thanks in advance.
