After three trips to Africa for plains game and DG,and winning some matches at Camp Perry in my youth, Here is my advice.
Forget your tripod. Use the PH's sticks as a bipod, not a tripod. Why a bipod? Because it's quicker and, more importantly, you can control your "natural" elevation by moving slightly backward and forward.
Forget monopods. I can shoot just as well offhand as with a monopod.
Practice: Shooting off the bench is a waste of time after you get a zero. Only shoot offhand or with sticks. Make your own sticks with two pieces of bamboo and an old bicycle inner tube.
Also don't shoot hundreds of rounds through your safari rifle. Shoot enough to make sure you don't get hit in the eyebrow with the scope, injure your shoulder, etc.
Then do what the NRA Highpower champions do. Dry fire at a spot you paste on the wall in your basement. The "muscle memory" you develop is transferrable. Or shoot a .22 that has similar dimensions and weight as your safari rifle.
I agree with Mccray. Take the .308 and not the "eargeschplittenloudenboomer."
