Need any more opinions? :-)

One thing to consider,the heavier premium bullets are designed to deliver deep penetration and hold together when delivered by belted magnums.

Not to say a 175 Nosler won't work...but but if you just hit ribs and lungs expansion may be minimal.
I'm usually a heavy bullet guy,but IMO,150's to 160's or so might be a range to look at.
Nosler book at hand,RE19 and a 150 gr partition will go 2831 at max,BC is .456,which is decent.
Consider a lot of elk have been killed by a 150 gr .270 bullet....277to .284 is a whopping .007 difference.Book max loads for .270 are 2900 max.70 fps isn't much.
Go up to a 160? Great 7mm bullet weight.Sierra makes some good cup and core hunting bullets that are fine for your velocities.Nosler makes a 160 partition.It goes about 2650.IMR 4831.
A Hornady interbond or interlock would work.

In a conventional cup/core bullet,flat bases are less likely to separate core/jacket than BTs

To sum up,you can use premium bullets,but realize they may be designed for holding up to 7mm Ultramags,etc.

A beauty about the good old 2600,2700,2800 fps cartridges is these velocities are happy for traditional hunting bullets.

Another important thought...You aren't shooting a.338 Magnum,so don't approach shooting an elk as blowing through shoulder bones or stem to stern shots.
Look for the shot that goes through ribs to the heart lung area.If you put a 140,150,160 bullet there at 7x57 velocities,you will make heart/lung soup.

It will work fine.I'm thinking,what you can find matters!!

Use some caution approaching max,but you have a large ring Mauser,use reasonably new brass,and a moderately slow powder like RE-19,IMR4350,4831,etc...your case/bore ratio is very moderate.
Do approach max with appropriate care,in steps...but IMO,I would get the velocity I could safely get.

Good luck!!
