Congrats on choosing to go on safari!
As others have mentioned the next year will be full of dreaming of the hunt. I would suggest shooting the rifle (375) as much as possible before you go. Make a set of shooting sticks and practice off of them….a lot. Lean on a tree for a rest. There are no benches in the fields of Africa! I think the longest shot I’ve ever taken or seen taken in Africa was about 280-300 yards. Most shots were probably about 150-175. If I have a long shot or am breathing heavily I will ask my PH to lean on me or stand next to me and I’ll lean on him with the rifle on the sticks. Seems to help keep my swaying to a minimum. I would also think seriously about taking that 7mag as a backup. For either a malfunction with your primary rifle or if you decide that the 375 isn’t as much fun to shoot and kicks too hard. I’ve seen 150tsx perform very well on plains game from my dads 7 mag. I wouldn’t hesitate to use it on any of the game you mentioned. African game is as easily killed as gamefrom anywhere else as long as you hit them properly. I’d also suggest study the anatomy of the game you plan on shooting. Basically shoot them all in the shoulder and you’ll be fine.
Good luck and save your money! When you start seeing all that game it’s hard to stop shooting!
Best of luck.
