Be aware though the two different bullets you are planning to use, MAY not work ie the rifle may not regulate. But worth trying.
Regarding recoil and fast shooting response, you are correct of course. However shooting my .375 I got the highest score on a local competition the first time for rapid speed shooting with a time limit. Everyone except one guy used medium calibres. Open sights only.
I agree while it is not apparent to many, there is quite a difference between a 1x or 1.1x scope and a 1.5x scope for speed of shooting.
Good luck with your new rifle, it is a beautiful gun, and good hunting with it.
