Paulinus,
my 9.3x62 lux came with two cross bolts before and after the mag box, it also has a barrel lug in an F block configuration. I had it bedded and floated to the barrel lug as it's quite a nice bit of wood and I did not want to risk it cracking.
On my .375 H&H I just had it bedded.
On the 9.3x62 I have a leupold 2-7 Vari X11 (old style) in warne fixed rings.....would have liked qd's then I would have quicker access to the irons, but reality is I would not use the irons unless the scope packed it in, and then I just gram the allen key and take it off.
Scope on my .375 H&H is the leupold 1-4x20 Vari X 11.....this is a great scope and very fast to use, I would have been happy with a 2-7 on this as well. I use cz mounts here and they actually work as qd's due the lug on the rear ring, they return to zero like warne qd's, they just lack a lever. Once again just have the allen key in your pocket.
I would discount the winchester after the ones I have handled, the M70 crowd will berate me, but the cz's are a more solid feeling rifle have integral scope bases and are a closer copy of the orginal mauser m98 action due to the self locking extracter. They also have one improvement over the m98 and thats the extracter cut is not through the lug.
