I upgraded to the same scope from a 4.5x14 40 and love the extra light that I get with the 3x15.I love the Leupold VX5 3-15 with Firedot. That Firedot feature lets me kill those big black hogs in very dim light. Black crosshairs on a black hog wasn’t working too well for me.
If you want an illuminated reticle, be sure it dials down to barely visible in dark woods. The adjustable brightness Firedot is perfect. Also good is the illuminated reticle on my Athlon Midas 2.5-15.
