Greggh, 175 gr. round nose bullets and a 7x57 is meant to be. Two friends of mine back in our younger years shot 7x57 rifles. One in a nice m-77 ruger and the other a well did sporterized mauser, Both used a 175 yr rn bullets for a while and the game piled up. Not one bullet was found in anything and that counts one large old bull elk, a 400 some pound black bear and several deer.
My observations when I was along twice for deer was an obvious hit and short well laid blood trail. Both buds claimed thats how it happens every time with anything.
Again, not overly long range neither. The deer I saw get shot were under 100 yards, pretty sure all game was under 200 yards.
