Some think my .416 is on the heavy side, but for me it's just about perfect. I see you agree!

My .416 was made by American Hunting Rifles, Inc., sort of a "gunsmith guild" type company run by Ed Plummer in Hamilton, Montana, USA. Ed came up with the semi-custom design and specs for his rifles, which are based on modified CZ 550 actions, and relies on a group of skilled gunsmith/subcontractors to build the rifles, subject to his overall supervision and quality control.
