Firstsafari.........If you use the 7mm mag, stoke the magazine full of 175 grain TBBC or Swift A Frame bullets. The bullet trajector difference at 200 yards is perhaps 1.5 inches! No big deal but that bullet really drives through tissue and exists most of the time on big animals.
If you decide you can handle the extra recoil from the 300 win mag, then use the 200 grain TBBC or Swift A Frame bullets. They simply penetrate deeper into the animals vitals and it's nice to get an exist wound as well.
I used a .338 win mag with 225 grn. TBBC bullets! Only one zebra had to be shot twice because of a sudden turn the animal made while I pulled the trigger and the bullet creased the shoulder. All other big game shots were 1 shot kills. I love the TBBC bullets, they mushroom to almost twice their diameter and they retain 85% to 90% or more of their original weight.
7mm mag reading in foot pounds of recoil to the body with a 175 grain bullet loaded towards the top of the pressure scale would be 27 pounds. The 300 win mag would be close to 32 pounds. A hunter will for sure notice the difference in 5 pounds or recoil to the body.
Most of your shots in the bush will be under 100 yards. However, in many places it is easy to get a 250 yard shot or further.
