Thanks John

My 500 is 10lb 10oz measured, plus factory ledger agrees. My 500/450 a few ounces lighter.

As far as the 450/400, my No1 was a bit of a pig until I put a Limbsaver on it. Purely stock design especially when using a scope! Is better without. If a rifle is stocked for open sights I find they slap me a bit when using scopes. My face is much higher on the stock.

I have an original early 375H&H belted Magnum that is something like 8lb 2oz, but is a joy to shoot. Stocked for the express sights of course.

Some interesting figures there. I would hazard that the recoil velocity and stock design are big factors.

Great topic.

Cheers, Chris
