Please explain how you "really limit yourself and the capabilities of your carbine / rifle with a 50-yard zero"...
If you look at trajectory charts, with a 50 yd zero, you are never more than 2" high or low all the way out to 250 yards.
With the 100 yd zero, there is no over, you are always going to be low up to and after 100 yards. But by the time you get to 250 yards, you are 6" low!
For defensive use, the 100 yd zero might be better, since at 50 yards out to about 175 yards, you will only be an inch low or less.. so only hold overs, no hold unders to remember. But honestly, either zero will work for self defense distances aimed at center mass.
