The VX Freedom series only has one shotgun/muzzleloader scope and it is a 3x9. Way to much power for a turkey gun IMO. The 1.5 x 4 is a rifle scope and is parallax adjusted for 150 yards like all their rifle scopes.
I looked around and found a used but like new Leupold VX I Shotgun 1x4 scope. It is parallax adjusted for 75 yards. They were made with Heavy Duplex and Turkey Plex reticles. Mine is Heavy Duplex and clear as a bell.
Excellent scope if you find one and well worth looking for. I have the same scope with the turkey plex reticle and the scope is bit sharper, a bit brighter, 5 ounces lighter, and wider field of view than my Nikon Turkey Pros. Eye relief is ~4", about an inch less than the Turkey Pro, and it has a smaller exit pupil, but still 10 mm at the 2x I run it at.
