RE lightweight Lott, mine is 8.5 lbs empty, and the loads are 2150. I can't shoot it all day, that's sure, but I can shoot it perfectly well and without an ounce of apprehension.

Big bores are not meant to be plinking guns, they are meant to be used against dangerous game. I carry my rifle for hours every day, several months in a year. My 450/400 at 10.5 lbs is more comfortable to shoot than the Lott, but much less pleasant to carry for any length of time.

If you have a rifle that you can shoot perfectly well and carry easily, you got yourself a tool. A 12 lbs anything is not a tool, it is a pain in the backside in dangerous game country.

My "lightweight" Lott is a tool, and a good one.
