Yes .257 is marginal for moose. That’s out of the way now. What’s your bullet choice for Ontario moose. 120 partition or 100 ttsx are available. Is my thought process correct? I’m thinking partition would offer better wound channel until nose is shed, which should be in the vitals of a broadside moose? but likely remaining core caught in far side hide and not exit. While the ttsx offers more penetration, and would likely exit but create a smaller wound channel in vitals.

Never would I hunt moose or elk with the 257 Weatherby, I have a 257 Weatherby for antelope and deer. My son and I are hunting moose this autumn with 300 H&H and 300 Weatherby Magnums, and nothing less. We match cartridges with the animals we are pursuing. I have two 30-06 for sale on EE, take your pick, it would be a better choice than the 257.
 
I would pick the partition simply because I'm more familiar with it. A couple of members on here with a lot more experience than I have are pretty negative on their reviews on monos in general.

Another member on here routinely hunts moose with a .25/06, so a .257 Wby should do fine. The difference between a .257 and a .270 is a piddlin' 20 thou and 10 grs of bullet weight, and nobody seems to question the use of the .270 on moose.

I too would choose a larger caliber for Moose too...
Plenty have been taken with .243, but likely by folks who have only ever used it their entire life.
The video suggests the bullets performance and the wound channel it makes.
Many an animal has fallen to the Barnes bullet when the bullet is used in the appropriate gun for intended choice.
Imo the 257 is less than marginal for Moose after 75 yards.

 
The purpose of a Nosler Partition is to open up and deliver all energy to the animal. I've hunted deer with 150 and 165 gr .30 cal Partitions, and most of the time the base stayed together with the nose opening out. But ... moose hide and anatomy is tougher than a whitetail. For that reason, I'd argue for the solid bullet in a smaller calibre load - not that this is a cartridge I think is appropriate for an animal the size of a horse.
 
Moose are not hard animals to put down.
I have taken four or five Elk with the 257 wtby 100 gr Barnes ttsx so that's what I would use for Moose

Basically how I think too. Put the right bullet in the right place. I know where the right place is, just to figure out which bullet now. The rifle budget is basically a surplus budget. Yes, the next rifle will be better able to handle moose duties, likely another 35 whelen which I still have ammo for. Farm has been going good so far and it’s looking like I’ll have plenty of time to occupy myself picking blueberries this summer, which seem to be looking really good at this point and I think we’re beyond any frost danger. If things turn sideways and there isn’t $$, the weatherby is going and I won’t loose any sleep over it.

Those using a .270 Win. on moose generally use the 150-grain bullet (and some use the 160 partition). Since the heaviest .25 caliber hunting bullets seem to be the 120s, there's a 30-grain difference between the .270 and the .25s. In my view that's more than a piddlin' difference. In my experience, the .270 Win.--loaded with good controlled-expansion bullets (like Nosler partitions and accubonds, and Swift A-frames) to top velocities--is a viable moose round. The .25s, not so much.
 
I’ve used the 270 win and 270 wby with 130’s in elk for years and wouldn’t hesitate to use it on moose. I also know a guy who uses the 25-06 on elk and a guy who’s shot more moose with a 243 than most people have ever seen!
Partition or Ttsx, take your pick in the 257 wby and put it in the right place.

How do you know that? I know lots of guys who have taken moose with 130’s in the 270.

Well, I haven't done a survey.;) However, almost all guns/hunting writers and bullet makers (all that I’ve read) discussing the .270 Win. recommend the 150-gr. bullet for moose and elk. And why not? Sure, a well-placed 130-gr. .277 bullet will kill moose, but a 150-gr. bullet is just a little better—more room for error, better penetration through heavy bone and thick musculature, so more dependable terminal performance, particularly on steep quartering shots—with its considerably higher sectional density (.279 vs. .242 for the 130) and generally better ballistic coefficient.

Getting back to the original discussion, the 120-gr. .257 bullet, with its lower weight and lesser SD value of .259, doesn't come close to a 150-gr. .277 bullet. Sure, it will kill moose with a very well-placed shot and the hunting gods smiling, but why use a sub-optimal round (unless, I guess, you have nothing more powerful)?

That’s actually not the original discussion..
 
Marginal in that despite the hyper speed, energy drops below the generally accepted 1500ft/lbs desired for Moose. This is true of either of these projectiles, without looking I'm thinking, you would be under at about 300 yards. So like 50 or so other calibers, the question is, do you have the ethics and judgement to pass a longer shot.
