I mounted the Millet rings on my CZ550, 9,3x62, and they are
darn near impossible to keep tight! Even checking as often as
I did, they still flew off the rifle during a shooting session
of 286-gr TSX bullets. Anyone who owns a 9,3 KNOWS the recoil is
nothing like a 375 H&H.
Anyway, I've since ordered some Burris CZ550 rings and they
snug up nice and tight. The down side was when I was removing
the Millet rings, I'd tightened them so much I destroyed my scope.
My new scope should be here towards the end of this week so I
can finally finish up my load development and chronographing.
Only have one more bullet to work with: Barnes 250-gr TSX.
So far though, the 286-gr TSX is very accurate, easily get
2330 fps MV(five shot aggregate), which is sufficient for my purposes.
I'm in a crunch for time at this point, but I may have CZs
scope "bases" milled off, and have the reciever drilled & tapped
for a better quality of base at a later date.
