Thank you.Depending on your twist rate, your rifle may not be stabilizing the bullet fully. At the speeds you'd be able to push the 175 to in a 7x57 in a standard 1:9 twist barrel, Berger's calculator says that it's only marginally stable and should have a 1:8.25" twist barrel.
Woah! When did they release a 160?You are probably right on the edge for stabilization. If you can't find your desired results, consider the 160 gr AB and the new 160 gr BT. Both have decent BC and great on game performance.

The 7mm 160 gr BT was released last year. I shot this doe with the 280AI and the 160 gr BT. DRT!Woah! When did they release a 160?
I wish I had known about it all this time, though I probably wouldn't have been able to find any for sale. I'll need to work up a load with them in my 280AI. What powder were you using?The 7mm 160 gr BT was released last year. I shot this doe with the 280AI and the 160 gr BT. DRT!
I think the 160 gr BT would be a great choice for your 7x57.
