Many shooters buy "premium" bullets to get the best performance, but its not always necessary.
I do the same many times, ( my favorite and most trusted "go to" is the Nosler Partitions in any caliber I can get them in. Sadly I have some rifles that use bullets Nosler doesn't make) But I am interested in the hole being through and through, and the wound being of good diameter. Other than those 2 things, there is nothing else to worry about. A bullet that retains 99% of it's weight doesn't kill anything better than one the retains 50% of it's weight if both make the same diameter hole and both exit.
I have a tendency to go toward Nosler Partitions the larger my quarry is, or the smaller my cartridge is. I LOVE premium bullets if I use my 25-06 for game over 200 pounds, but if I am hunting elk, a 30-06 or a 308 or 300 mag with a 180 grain to 220 grain bullet is usually going to be just fine, and with my 375H&H any bullet made to go in that cartridge is good on elk. Even the ones that come apart some sill kill elk like lightning.
I bought 15,000 150 grain Winchester Power Point bullets some time ago (1985) for use in my M-14, M1 Garand, FAL, and 1903 Springfield rifles because they were as accurate as I could hold them, and they were cheap back then.
Well in the last 3 years I started using the few I have left in my scoped 30-06 Mauser, and my scoped Mossberg 308.
I have now killed 4 deer, loaned the Mossberg to 2 hunters who have killed 3 more deer with it, 6 antelope and also 2 elk. As a rule I like 180 or heavier 30 cal bullets on elk, but the circumstances worked out that the Mossberg was available in a moment of need, and that was what it was loaded with and zeroed for. So 150 grain WW Power Points were what was used for those elk.
These bullets passed clear through every deer and every antelope including a few shots that were not broadside, and broke bones in several. I have no idea what the retained weight is because I was not able to recover any of them. (Exactly what I want in a big game bullet)
On the elk, both were shot 2 times each. Both had one exit and one bullet stayed in each animal. One weights 131 grains and one weight 129 grains after they were recovered. That's as good as I have seen from 150 gr 30 cal Nosler Partitions over the last 50 years of hunting and guiding.
These days they cost about what most other standard 150 grain 30 cal bullets cost, but in 1985 when I got them they were about 70% of the cost of most of their competition. So they were a "cheap bullet" but they sure don't act like it.
I have killed antelope, deer, elk, bear, and moose with Nosler Partitions, Speer Grand Slams, Barnes X, and various other bullets. I have to say these Winchesters 150s do as well as any 30 caliber bullet I have used of 150grains, regardless of brand. That is not to take anything away from the premium bullets I have used and seen used, but these Power Points are just a "plain vanilla" bullet, but they seem to think they are an ultra-premium bullet.
In my Mossberg with my best load, I can keep 5 of them touching at 100 yards and at 200 yards I have shot 2 groups that were 1.18 " and 1.2" so they lack nothing for accuracy. You get what you pay for most times, but I got a lot more then I paid for.
And that accuracy from a rifle that has only a Weaver K4. They could be even more accurate, but with a 308 with a 4X there is no way for me to know that for sure.
But I also don't care it they could be more accurate.
Just over 1" at 200 yards is plenty good enough for me.
