makes for a very quiet hunter…why? 2cc case capacity means you can launch a 300gr .338cal HPBT with 10.7gr of X powder to get 1,000 fps vs 14gr of the same X powder in a 3cc case…pressure doesn’t build up by how much powder necessarily, but by how large or small the container holding that charge is. Air density and positional sensitivity also play a role in the cartridges ease of obtaining consistent fps and low SD’s.
