Scope for both bolts and projectiles?

If I had a gun in .30 cal and an archery set up, is there one scope that could be used for both?

New and trying to learn.

Yea. Something with a MRAD or MOA reticle has worked for me. Reference the following thread for details:
 
@DoolyTiger After re-reading this post, when you mentioned “an archery setup,” were you asking about a scope for a crossbow? My mind went to airbolts and I may have misunderstood. If so, there have been discussions about using crossbow scopes on airguns. I don’t know much about that and thought an archer might have a better response if one hasn’t already chimed in.
