If you were hunting black bear, elk, moose which would be a better game getter?

A Remington 700 in 270 with 150 gr Nosler Partitions? Shots at 250-300 yards max.

Or a Mauser 98 in 8x57 with 200 gr Nosler Partitions? Shots at 200 yards max

I don't think you could go wrong with either one. But just based on personal bias I would go with the 98 in 8X57, cause I already use one. Only difference is, that I prefer Accubonds. I also wouldn't limit it to 200 yards.

I wouldn't limit the Mauser at 200 either, it will do fine way farther out than that.

Honestly, they're going to be pretty close to equal. The 8x57 doesn't have the respect it's due in stronger rifles. It can do pretty much what a .30-06 can if you handload and have the right rifle. I load both, and quite honestly I think either rifle will do. The 8mm might be a little better, but like I said, it's got to be in the right rifle and loaded closer to .30-06 pressures. There is plenty of info on the web out there.

Here's what Chuck Hawks has to say on the matter: http://www.chuckhawks.com/forgotten_8x57.htm

^^^ Exactly! Load to CIP specs, not SAAMI specs. As long as you have a .323 bore.

8mm because you added moose to that list.

the 8mm and 7mm mauser rounds are excellent.
i would go for either

They are awfully close in comparison. I have been loading for the .270 win for a very long time and know what it's maximum and practical capability as a hunting weapon on big game is, which has been historically very good for me. But I wouldn't hesitate to hunt elk or moose with the 8x57 with the right action, and the right reloads. I actually believe that the 8x57 could produce a slight advantage over the .270 win., because it can deliver a heavier bullet at velocities slightly greater than that from a .270 shooting a significantly lighter projectile. I think this would likely produce better penetration.

This is a common misconception. If you have bullets of equal, or near equal weights fired from different caliber guns the larger caliber gun will generally shoot them faster. You can shoot heavier bullets in larger caliber guns at about the same speeds as lighter bullets from smaller caliber guns. This is all true

150 years ago when projectiles were simple lead balls or cones this was important to ensure penetration in game. With simple lead projectiles heavier always out penetrated lighter. But with modern bullets not so. Bullet weight is still a factor, but construction is far more important today. Weight is only a factor in that within the same caliber, heavier bullets are longer bullets.

A 270, 30-06, and 8X57 will all shoot 150 gr bullets at, or just under 3000 fps. But because the 270 bullet is the smaller diameter, and longer bullet it will always outpenetrate the other 2 if all are using 150 gr bullets. Because it is more aerodynamic, it will maintain that speed better and will be MUCH faster and shoot MUCH flatter as range increases. With larger diameter bullets you have to move up significantly in weight to get equal penetration. The trade off with heavier, slower bullets is a more arched trajectory.

Generally speaking longer bullets penetrate better. A 270/150 gr, a 30-06/180gr, and an 8mm/200 gr are going to all penetrate about equal amounts when they hit game. It would be about a wash with all 3 assuming you were using the same bullet in all 3. Start shooting a Partition or TTSX in one and a Hornady SST in the others and then it becomes a matter of which is using the better bullet, not the caliber, speed or bullet weight.

We should sticky this above!

First of all, NP's generally out penetrate Accubonds, so you have chosen the right bullet for the "bigger" big game.

No question, either of your two would do just fine, but the 270 will have less recoil in equil weight rifles and for longer ranges, it would be my first choise.

As a side note, i've harvested something close to 30 big game animals (includeing moose and blk bear) with my 8x57 loaded with 200NP's...
