Arizona,

Kynoch lists .375 Flanged at this URL:

http://www.kynochammunition.co.uk/

Weights:

Merkel 323E .375 Belted Mag. - 9.24 lbs. No scope.

Ludwig Borovnik .375 Belted Mag. - 10.46 lbs. w/o scope; 11.82 lbs. w/ 1.5-6 Swarovski scope.

Holland & Holland Royal Hammerless Ejector .375 Flanged Magnum - not yet weighed!

I'll have to remember to weigh the H&H and maybe report back. I would guess it weighs an amount similar to the Borovnik.
