I'm taking two rifles: 30-06 WWII Springfield for plains game and a Mauser 98 in 404 Jeffery. Everyone encouraged me to hold out for a magnum action when I built my 404 (everyone but Duane Wiebe, a custom gunmaker from Bellingham, WA - he was confident I could handle converting a 98). I'm glad I followed my heart and went with the shorter action. I'm not sure about the cycling speed but if the gun were any heavier I'd have to hunt with a forklift.
If you can get to a skeet range and practice shooting clays low gun (target pulled with gun down in ready position, mount, acquire, and fire), that will benefit you greatly. Shooting moving targets is apples and oranges compared to shooting off the bench or sticks. Like a skeet shotgun, your rifle and sights (scope or iron) need to fit perfectly for shooting moving targets. Yes, skeet is shot with a shotgun not a rifle but the principles are the same. The problem most folks have with shooting moving targets with a rifle is lack of follow through. Skeet should help with that. Maybe I'm presumptuous. Perhaps you know all this already. Hope it helps ... someone.
PS: When you can hit targets consistently low gun from skeet station eight, you are ready for charging buffalo. More than ready. I'm old and half blind so I usually shoot that one high gun.
