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

Since I carry my rifle for hours every day, a few months per year, the 8.5 lbs is a decisive advantage over my 450/400 at 10.5 lbs. The 450/400 is significantly more comfortable to shoot, but much less pleasant to carry for any length of time.

If I want to do long sessions at the range, I select a more adequate caliber, like a 7x57 for example. Big bores are not meant to be plinking guns, they are meant to serve a purpose in dangerous game country. If one can shoot his rifle proficiently, AND carry it easily, he's got a good tool.

My "lightweight" Lott is a tool, and a good one. A 12 lbs anything is not a tool, it is a pain in the backside if used for the intended purpose.
