OK I see now.

Like their old 275 grain 338. Not popular enough to keep making them, but I killed an elk with one of them from a 338-06 and the performance was wonderful.
Today I think I'll have to settle for 170 to 200 grain bullets in my 8X57. No big deal I'd bet.
If I ever want more weight than 200 grains I can use the 220 in my 300 H&H, or I can simply use my 9.3X74R or my 375H&H.
I have seen the effects of 180, 190 200 and 220 grain 30 cals on elk. I know these bullets have more then enough weight for the job, if they just hold together at least 60%.

I have killed elk with 150 grain 30 cals and a number of 150 and 160 grain 270s. Never had a failure with any bullet that holds together. In fact, of all the elk I have killed with my 270s I have only ever recovered one bullet and that was last season. All other 270 kills gave me exit wounds

I have friends who have killed a number of elk with .264 and .257 bullets too and they did fine if the bullets hold together.

I know one boy who killed 8 elk with a 243. He killed 5 with factory loads and said they died ok, but the bullets didn't go as deep as he thought they should, compared to his dad's 30-06 He went to 100 grain Nosler Partitions and said that the last 3 were a lot better. No exits, but the bullets were against the hide on the far side.

Anyway....for my 8MM I expect I'll be happy with what I have now. The SSTs are super accurate but I am not 100% sure how well they will hold together. I guess I'll find out.
I do have a number of others to try, but it will take a few elk and a few years to know all of them for sure.

I have some 200 Gr Nosler partitions which I have 100% confidence in.

I have some Hornady 180 Grain GTX mono-metal bullets which I am 100% sure will be fine at all ranges they will still expand.

I am 60 years old now, and it's a sad fact that I will not ever be able to hunt enough game at enough ranges and enough terminal angles to know the details of every bullet at every range with every rifle I like, but I am still having fun with the hunts and I love gaining the knowledge of the technical aspects of the bullet performance too.

My problem is simply that I lack enough money to hunt 50 animals a year, and it's unlikely that I will last 85-100 more years.

Sad... aint it?
