I have a brand new Leupold mk4 4.5-14x50 LR/T Mil-Dot new in box never mounted i am considering selling for a viper PST 4-16x50 FFP i like the leupold but does not have the featured that the vortex has like zero stop and FFP, i will be using this scope for deer hunting and target practice on a .243 win custom built for the 115gr d-tac, should i keep this scope or go with the Vortex, i could sell the one i have and get a vortex and great rings for less, good or bad idea? never shot with a vortex is the clarity and light gathering as good as the leupold? are the clicks as trackable? what would i be better off with? my big concern is the ffp on the vortex for hunting i could get my drop on the reticule and it be the same thru the power adjustment in the case of having to make a quick shot on an animal. looking for Vortex user opinion. would i be losing quality by doing this?
