Answer a couple questions.
- what are you hunting
- what is the furthest shot you are comfortable taking and might actually take
- what is the expected impact velocity
1. Roe deer, fallow deer: 30-06, nosler ballistic tip, 180 grains. Up to 200 meters (my comfort zone). Then Red deer, wild boar, 9.3x62, usually in woods, closer shots, 50 meters, 100 meters. Soft points, 286 grain.
Africa: 375 HH, swift a frame.300 grain. (ok its not everyday backyard hunting, but occasional.
Note, I dont have magnum rifles, such as 300 win mag, or faster. If I had, I would be using different ammo. I dont see the point in such calibers for my average hunting distances.
2. Furthest shot, comfort zone 200 meters, standing, from stick. Maybe a little over. Generally my local range is 200 meters, I train up to 200 meters regularly, and in the field I am not pushing much more then that. I had few shots, over 200 hundred, but if the rifle is zeroed at 200 hundred, then point blank range could be around 230 meters, or so. I have access to another 600 meters range, but it is not for any training for hunting. Prone position, target shooting, different rifle set up, 308 win. So, for hunting, irrelevant.
3. impact velocity - velocity of bullet at target, taken from ballistic tables, for each distance.
I shoudl add, that few seasons I tried hunting in 30-06, with bonded bullets. (norma oryx), effect on game is very good, but I did not see difference when compared to ballistic tip. (roe deer, fallow deer)
For Africa, (375) my reasoning is following. Hugh quality bullet, that keeps mass. SAF. First trip was for eland with that bullet. I took two elands. One for meat, another for trophy. So, non trophy eland was first shot broad side, pass trough. He turned, I took nest to the chest. Bullet whent through entire lenght of body and was stopped under skin in hind leg, with perfect mushroom.
Trophy eland taken from back in high neck broken spine, dropped in track.
So, basically, appart from neck shot (to break spine, any bullet will do), in such caliber and for tough or large game I expect penetration, and holding the mass. Next target I hope for buffalo
