something I can't fathom is how people can spend thousands of dollars on a hunt, sometimes thousands on rifles, optics, and all other kinds of gear. and in the same breath, will put a box of Remington core lokts or another budget cup and core bullet in their rifle. And what makes that worse today is that there are affordable premium bullet options now, even in factory ammo, such as the Federal Fusion which is still affordable but uses a better bonded bullet. and I can't deny that standard cup and core bullets are proven for many kinds of game such as whitetail and smaller big games. however, I also can't deny that a premium bullet of any sort will still work better on any game species larger.
I know I'm kind of preaching to the choir with this one but I rest my case.
Some random thoughts.
1. Ignorance
2. Using rental camp rifle, will leave you no choice in bullets. When you are in camp, you will use whatever they give you. If you dont bring your own.
3. Medium to smaller game (up to 100 pounds in weight), will better be taken with rapid expansion bullet, which is usually cheap. For example I hunt roe deer exclusively with nosler ballistic tip 30-06 . In the same time, for Africa, my choice is swift a frame. My choice is based on game species that I hunt, combined with caliber nominal energy and velocity. I want best performance, and humane kill, Nothing wrong with nosler ballistic tip for roe deer in my own heck of woods..
4. Premium bullets are for magnum speeds, or for thick skinned game.
5. There was no need for premium bullets 100 years ago, when bullet velocities were around 700 m/s or less. For example, I hunt wild european boars with classic soft point, 9.3x62, velocity 700 m/s (2296 fps) and conveniently, SP is also economical. But If I would be using 300 win mag for same purpose, I would use premium bullet. Bonded, monolithic or partition. I dont mind spending money on ammo, but not every premium bullet is necessary for every purpose.
6. Other group of people is those who dont spend time and money on international premium hunts. Those who hunt in their own backyard, and are of lower income. This may come together with ignorance. Cheap bullets. if one bullet cost 1, the other 5, why paying 5? lets pay 1, and go hunting.
There were two notable stories, when premium bullets were needed.
The story of mr Grey, who wounded lion with 280 Ross (3000 fps) and wounded lion mauled him to death. this ended the reputation of 280 ross caliber.There was no premium bullets available at the beggining of xx century. Mr grey, couldnt use anything better, except to use some other caliber for that occasion.
Second story is when John Nosler had a problem killing a moose with some soft point in caliber 300 HH. Moose refused to die, till after about two magazines emptied in him, and with hardly any lead getting to vitals. Close range shooting. (high impact speeds, magnum velocities)
This event motivated nosler to design his famous partition bullet, If he was using 30-30, or 30-06 on the moose, he might never get the idea. The rest is history.
Both stories describe problem of soft points and magnum velocities. Go down in speed, arguably you dont need premium ammo in general
