Might as well stick to the same caliber. I like my St. Louis Hawken in 58 but the enfield Musketoon is a charm to pack around in the woods. It is so light weight. The Zouave gets real heavy and is awkward in a vehicle but an old "Buffalo Hunter" is nice and really loves the PRB in .570. The Toon likes the Lyman 577611 over 90grs FFFg. The 'Toon does indeed shoot clear through an elk.
