On the first few hunts with the 7x57, those old Win loads with the 175 gr RN were all I could get - and were deadly on deer/elk. But, once started reloading and testing loads, I found that weight/shape bullet to be quite less than optimal for overall performance. Eventually figured out that, in my 7x57s, the bullets designed for hunting and weighing it at or near 140 gr, were optimal. YMMV.
