I don't shoot centerfire rifles often, so every time I do I'm struck by how loud they are compared to shotguns and how much concussion they create. The muzzleblasts seem to flatten the grass around them. Even when I am sighting in a slug gun and people two or three lanes away are shooting ARs I can feel the noise. Why would anyone want to make a rifle louder? Beats me, but sometimes it's best not to ask why.
