PC,
In that case the recoil of the 9.3 would be considerably less as your 375 CZ would weigh about 10lbs in comparison to your 9.3 CZ at about 8.5lbs. Would that be correct?

If one was to compare them in the same weight rifles the difference would be significant. I guess therein lies the beauty of the 9.3 - similar performance in a lighter package with less recoil for those who are sensitive to it.

I have cz's in both 9.3 & .375 and the 9.3 does recoil less.
