I thought I'd poke my head into this thread. This summer, I'm going to Africa for my first plains game. My only hunting rifle is a Tikka T3 Lite in 7mm Rem Mag. I'm happy with the rifle and my ability to shoot it well for most all of the game they have, but I'm a little concerned about Eland. If Eland is the only large game I'll be taking, would sticking with the 7mm RM be okay if I use the right bullet and stick to <150 yard shot? I've got 10 days to hunt a 22 square mile ranch, so I don't think I will be rushed into making a sub-optimal shot.
Otherwise, I'll probably purchase a second gun for Eland/Moose/Bear (in something medium-bore like 338 Win Mag).
On the other hand, I could skip the second gun and just add a true dangerous game rifle in 375 H&H or 416 Rigby, but having never fired serious cartridge like that, I'm a bit concerned about recoil. I don't have as much mass to soak up the foot-pounds as most of the other African hunters I've seen. I'll head up to my friend's land in Vermont and try his. That'll pretty quickly determine whether or not I want a gun like that.
apologies if this is considered a threadjack.
