Yep, I too have a 1.75-6x Leupy in QD mounts on my .375. Currently Leupy QR mounts, but intend to move to Talley in due course [i.e. when the dust over the Oz Post import debacle settles].

I like the notion of having the mount release levers on the opposite side to the bolt handle - not possible with Leupy QR's on a LH rifle.
