Bill, list:
A couple years ago I shot a moose with a 220 grain X-bullet from an 8x57 mauser. Behind 47 gr of 4895. This is a load that splays the primer out of the pocket a bit, and that is somewhat hotter than max 220 gr. loads in the '06.
I shot him head-on in the brisket. he jumped and took off. It was at the top of a drainage - I followed the blood, then searched the whole drainage looking for him. Didn't find him so I went back up to where I shot him. I found him about 25 yards away, he doubled back and I missed him in the brush, first time.
I dressed him out on the spot, found the bullet under the hide, right side, about the last rib. It had expanded to about 1/2" is all. I could have hammered the point back together and used it again.
I never did find that animal's heart. It was a clean kill.
I used the X-bullets because my brother gave me 20 of them. Idaho, you can use lead for big game. I used copper because I had some.
I'm not certain if the bullet was at fault. At first I thought it maybe was designed for use in the 8mm Rem mag. I realized later that I had primed those shells with some of the large rifle magnum primers I bought during the **last** primer panic, when Bill Clinton was prez. I gotta get a chronograph.
Anyway, Bill, list, copper bullets are probably OK. they will definitely stay together going thru a shoulder, even on an elk or a big bear. As far as expansion goes, that's another matter. This year I used jacketed lead bullets in my 7 mag and my 30-40.
Bill, moderators - I'm glad you're cutting the hunters some slack on this site. Hunting with milsurps is an american trAdition. Back when a Model 70 was $100, you could buy a Kragfor $10 and take an elk just fine. Milsurps are the people's hunting rifles.
