But really its a wash, cause the power will most likely be set on 5 or 6
for the most part,and that will pretty much give a 4 inch eye relief or close to it
To be honest my 3x10 scopes are only ever used at 3x or 10x.I always have my scope set at 3x and if the conditions call for more magnification,I adjust it to 10x.I never use the settings in between.
