RE: Bushnell ELITE 4200 vs. Leupold VXIII....
The 4200 is much clearer, brighter, and crisper than the Leupolds but they only have 3 inches of eye releif.
Before you buy you should also take a real hard look at a Burris signature select or their top of the line Black diamond. Either of these two lines beats a Leupold of Bushnell.
