I've got an 8.5 twisted Rock on my 7. Shoots about anything 160 or over very well. I'd try to avoid shooting a ram where a large exit wound could be difficult to repair. The nice thing about the 8.5 7 with heavies is it does reduce the need for exact wind reads.
I like 168 hybrids. Shot a whitetail buck in his bed at 35 yards. Bullet went in right under his chin through the throat patch. Bullet exited out back of his very thick neck with about a silver dollar sized hole. Close or far, I am shooting bergers till out of them, then trying 180 scenars.

The 140s and 160s shot amazingly well in my 7mm RM and also do well in my 280AI. The 7mm RM loved Re22 and IMR7828. I'd give some of the newer more temp resistant powders a try, but not sweat it too much.
Can't go wrong with either weight in 7mm. The rifle will tell you which bullet and powder it likes.
Agree that confident, quick and accurate engagement is key to really any shots on game. That means lots of practice from every field position you can imagine. Get off the bench once you choose the load and never look back.

I'd certainly give the new 150 gr. Nosler Accubond Long Range myself. Will work on the short range shots and might give you a bit more on the longer ranges.

I use the Sierra 160 gr Gameking hollow point in my STW as well as my 7 ultra mag. it has performed well in the wind and killed DRT on every Deer I have shot . Sierra specs say its a lot harder than most hollow points and is designed for mags. I zero for 300 yards and made a 450 yd shot in a 15 mph wind 90 degrees to my barrel by holding a foot left and a foot high. 250 lb 8 point. Hope that helps to show you drift and drop .
SHOOT STRAIGHT AND OFTEN. Hunt with your kids. Teach them not to shoot anything that they are not going to eat. Have respect for all ANIMALS.

Almost anything from 160-180 grains should do it, or even 140s and up. I would be tempted to throat it for 180 Bergers and 160 Noslers as the Berger can be the more finicky. Just make sure it isn't too much freebore for the other bullets. I just go with what the gunsmith likes after providing a couple dummy rounds.
But lots of other choices too.

Sako what happened to the original trigger (grin)?  Only kidding. Anyway as far as Partitions not shooting is concerned we know they shoot in some rifles. I have never seen them NOT shoot in a good custom barrel.I have noticed they like to be seated straight meaning I've seen a problem load go from mediocre to very good if runout was kept low. The other thing is I have seen them start to shoot as "top end" for the cartridge was approached,and often you can watch this happen on the target. That said a combination I have liked the past few years in the 7 Rem Mag has been the 150 gr NPT and the 150 BT. Pushed to about 3150 both bullets have shown very good accuracy and in my rifles POI has been the same to 500 yards where the BT will hit very slightly higher (maybe the width of my hand). Obviously the 160 AB would be another great choice. Personally I'd use the Fed215 primers. Powders are 7828, H4831,and RL25. Have not tried the new RL powders designed to be less ten sensitive. Bob's always straight to the point and spot on. I don't think I've ever had a rifle that didn't like partitions. Even the blemished/seconds that SPS sells, have performed flawlessly. The new owner of the 300 wsm I recently sold was tickled chitless when he loaded up some 180gr. blemished partitions (that I gave to him to try out) and he says the rifle shoots into .6" consistently. Back to the 7mm rem mag: I just bought a couple hundred old Hornady 175gr. sp interlocks to try out. I'm hoping my rifle likes those as it seems like they would also be a damn good bullet on critters...
I try to stick with the basics, they do so well. Nothing fancy mind you, just plain jane will get it done with style. You want to see an animal drop right now? Shoot him in the ear hole. BSA MAGA

Hornady's 175 grain bc looks like .462? That is something.

My friend has nearly 22 preference points for Big Horn Sheep. He is currently building a new custom rifle in 7mm magnum, and is a very experienced hunter. The twist rate of his new rifle is 8.5".
I am on a mission to determine what bullet choices he should consider, should he get drawn in the next few years.
Items to consider.
He is comfortable shooting up to 450yds-500yds
Wind
Elevation
Drop animal in his tracks
Cape damage
Proven
Your help is greatly appreciated.
On the hunt of a lifetime, I'd be hard pressed to use any other bullet besides a Nosler partition. The standard by which all other hunting bullets have been judged for over 60 years. They work as designed every time.
It is irrelevant what you think. What matters is the TRUTH.

But a Partition might drift 3" more at 500 yards!

Wow sounds like a well thought out blueprint and an amazing opportunity!
If I were building something like that I'd skip over any of the ping pong balls. Even if he is setting such reasonable limits upon himself as 450-500 it still makes sense to keep drift at an absolute minimum.
175 LRAB if he is against "using target bullets for game" as some are; otherwise a 162 gr AMax, 180 VLD or Hunting Hybrid would be my first choices. As has been pointed out, that thing ought to shoot anything and everything really well so the choice ought to be his.
I hope we can see results of the build and ESPECIALLY the hunt!

dawaba: Yes I have heard sheep are not tough to kill. My guess is all would work well.
The 280 Remington is overbore.
The 7 Rem Mag is over bore.

If the Partitions "won't shoot", put one notch faster powder under them and try that. Usually it'll work without having to jack the pressures way up like with a slow powder.

I shot my 9 year old ram with archery tackle at about 32 yards. Wind was not a factor. If the OP is posting about building a custom fast twist 7mm for long range opportunities than it doesn't seem to make a lot of sense to not use the best bullets for long range shooting. Doesn't matter to me, my ram is peacefully hanging on the wall.

Which might save the hunt if you read the wind wrong. :-) Or a yeti might attack, in which case the stem to stern penetration of a Barnes will be needed. Neither of the circumstances above is going to happen, so just load up a Partition. Or a Hornady Interlock. Or whatever. Get in shape. Shoot a sheep. Take lots of pictures.

Saw the aftermath of a 139 hornady from a 7 Rem Mag on a nice desert ram earlier this month. The ram was DRT at 178yards and the cape damage at the exit seemed minimal as we skinned it for a full body mount. I'd go with whatever was most accurate in the rifle if just for the confidence factor...
Too close for irons, switching to scope...

Only one I saw shot with a rifle dropped with no exit from a 7mm 140 ballistic tip.

I shot a Dall with a single 139 gr Hornady out of a 7mm weatherby. Sheep aren't very tough at all.
I would use a 150 gr Nosler BT and be done with it.
