There is an indoor range opening in Dublin on Dublin BLVD across the street from Big 5. I stopped there this weekend and they plan to be open after Memorial Day.
I am guessing that it will be mostly handgun / light duty rifle like .223 or similar, still any place to shoot is good.
I cannot remember the name of the place but it is for fishing and hunting. My son said - "well, we know where to find Dad".
