My initial 'go-to' load for any 7x57 involves the 154-gr Hornady. That particular bullet has proven to be one of the most consistent performers for me in a number of military barrels and it's reasonably good on medium game up to 300 lbs. It's not always THE most accurate in every barrel but it's proven to be very consistent, to the point where I try it first and if the rifle won't shoot it then I trade it off 'cause it probably won't shoot anything else either.
