i harvested 1 5x5 bull with a 348 grain powerbelt. elk was slightly quarting toward me at over 150 yards, shooting downhill hit him a little high behind the front shoulder and bullet lodged low in offside hind quarter. i am a firm believer pour powder is best used with a powerbelt due to the cup on the base. hunting in Co. had to use a full bore bullet and open sites. ranged the shot after the fact at 159 yards. i was using a Knight Wolverine, added a thumb hole stock and a recoil pad for the extra length. still hunt with that MZ to this day but has Luepold 3x9, still shoots great whatever i run thru it.
