Exterior finish - hunting may have some gloss to it or some trim (leuopold's gold ring), tactical will go out of its way to be "nothing black"
Cross hair choices - hunting will almost always be a basic Dual-X type, or maybe single post and cross hair. Tactical scopes will get you mildot, holdover marks, etc
Other features - illuminated cross hairs or enhanced w/ dot, more likely to find FFP on tactical types, etc.
Things like side focus or adjustable objective I tend to see on higher mag scopes vs. not on lower mag scopes. Of the "tactical" style scopes like this the big difference seems to be in cross hairs.
