I have had a few of the CZ 550s, nice rifles. The 416 Rigby I owned was very easy to handle/shoot, wouldn't want it lighter. I bought my SIL of German heritage ( his grandfather fought the Nazis with Marshal Tito in Yugoslavia, then he immigrated) a CZ 550FS 9.3x62. I even had a scope with the German #4 reticle on it.
Someone did buy that Mauser Whelen on GB! I hope they enjoy it, looked like a good rig.
