Re: Ammunition question
Although my answer may not be what you want to hear, I'm not sidestepping your question. Your question is valid, and many people have tried to find the answer.
If there were one bullet to do just about everything, it would put all the other bullet manufacturers in a very difficult position as their sales would take a horrible hit.
Even with hunting bullets, there are bullets for different types of game.
With match bullets, there are bullets that need to be jammed into the lands, and other bullets that need to jump to the lands for best accuracy.
I think the closest you will get is to find a bullet like the AMAX that will work for thin skinned, smallish game like small deer, two legged varmints, coyotes and so on, and other bullets for elk that require deeper penetration.
For most medium to large game, a bullet that holds together and penetrates well is best.
For accuracy, each rifle has it's own preference, but usually the well known ammo makers offerings will do quite well.
