Vapo and ELK,

Thanks for the info. I thought it was just a stock difference but it never hurts to ask. I will be inthe market (next 1-2 years) to buy a rifle with a significant jump up in utility. I have decided that either the .375 H & H or the 9.3 X 62 would serve me well. I own a bunch of rifles in the smaller bore range from .243 up to 8mm and I could honestly dispense with most of them and keep only 3 of my aresenal and still be covered without so much overlap (but I will never lose any of them).

But it is in the upper ranges of the mid and large bores that I have nothing in the cabinets.

The .375 H & H seems to be a caliber that stepsup (for me)significantly in power and recoil but not so much that I feel I couldn't handle it with some instruction and practice. But I want to make sure that whatever I select is a known commodity since I don't usually shell out $700-$1000 for rifles.
I know that the CZ 550American in the 9.3 X 62 is MSRP $250.00 less than either of the Magnum models. But it comes with no sights.
Also, the recoil for the 9.3 X 62 is listed as a little lighter in the recoil tables. HOWEVER, I also noticed that the American is 2 lbs lighter than either of the Safari Magnum models, so the recoil on the less heavy recoiling 9.3 may actually feel worse being that the rifle is lighter.

Either way, after doing my reading and asking and thinking, ...I'm leaning heavily towards the CZ rifles.
