Hello Chuck,

following are some of my thoughts to your theme:

I have a shortened Sako in .375 H&H (22" barrel) and bought additionally a CZ550 customized to .375 Weatherby with a 24" barrel (63cm).

The Sako is nice to handle, shoots good and is a no-nonsense gun, and a little boring...

The 375 Weatherby has (at least for me) always power to spare and I can use 375H&H ammunition also if I get seperated from the expensive .375 Weatherby ammunition.
A friend of mine has also a CZ550 in .375 Weatherby (customized by the same gunsmith in Munich) and shoots foxes and roe deer with it. He reports no tight situations up to now, even some of those collected roe deer were weighing up to 30lbs...

Reloading for the .375 Weatherby was interesting:
I can obtain safely 837,5 m/s with the 300grs Hornady soft point RN with Rottweil R904 (approx. Reloader 19), and have a reduced loading of 800 m/s with the 300grs Sierra Gameking Soft Point.
If you are interested, I send you the data and we can interpolate/calculate with a ballistic program the expected velocity with the 350grs loads.

If I happen to visit Namibia in 2010 for plains game, I want to try the Weatherby, not the H&H...

best regards
Rolf
