Henry Repeating Arms Magnum Express, Lever Action, 22WMR, 19.25 Barrel, Blue Finish, Picatinny Rail Included, 11Rd H001ME With the proper bullet, .22 WMR is a super effective cartridge for small to medium-sized game out to about 125 yards. However, hitting a small and possibly fast-moving target at these ranges with open iron sights is a feat that could test even the most experienced of hunters. Magnification is your friend when it comes to hunting with .22 Mag, and the Lever Action Magnum Express takes out all the guesswork to get you up and running fast with a rifle that is optics-ready right out of the box.
