Rob,
I make a cherry shine but I have never used canned pie filling canned cherries.
Here is the recipe I use
Good Moonshine
32 ounce mason jar
I fill the mason jar with 8-10 ounces of seedless cherries with the syrup
Top off the mason jar with the good shine
I buy the cherries at my local grocery store – this is an example of the type of cherries I use- (cheaper at my local store)
