The Lyman Deerstalker is a great MZ. I have one in .54 caliber, and it is hands down the most accurate percussion sidelock I own, and that means it beats all of my many T/C models. It shoots a .530 roundball, with .018" pillow ticking patch, with 90 grains Goex FFG with great accuracy. I did put a Lyman 57SML peep sight on it, as I did not care for the leaf style rear sight that it comes with, but that's just my personal preference. You will not go wrong with one of these MZ.
