I once thought that with a crop damage permit that you caould shoot anything/anytime. My Father-in-law got one for his farm this year and the rules are very clear here in MD. Antleredless deer only (BB's are included in that) and you can only use what is legal for that area. Plus, once the huntign season comes in you have to use the weapon for that season.

Now the Amish might have different rules, and I'd check in to that if I were you, but as for the crop damage permit I think there are some misconceptions.
