Zaino? Never heard of if, please elaborate. As for the elk rifle in my arsenal, if I can't get close enough to get them with my .30-06 and a 165 gr. Nosler Partition, I'll hang up my boots! I can hit a milk jug at 400 yds. 9 times out of 10 with a 3x9 scope and the 165 gr. load, I practice, so I know my limitations, although 400 is maybe a little long for an elk and the .30-06, but it has done it on whitetails and mulies!
