I've been a member of Mill Creek and Penn Dutch.
I never really quit Mill Creek, it just lapsed and I didn't care. Rifle range has 8 benches, I think, and only goes to 100y. Pistol bay is small. There is an indoor range but you can't use it except for Sundays and you still have to pay. No guests allowed. Any fast shooting will have the neighbors (who are very close) complaining.
I quit Penn Dutch when after Sandy Hook they banned all semi auto guns. They have since retracted that rule but still, fuck them. It's a shame too, it's an awesome place. Multiple rifle and pistol bays. Rifle out to 400y. I just can't forgive them. *This is not right, I've been corrected below*
I was never a member at Manheim but I've done lots of their tactical pistol matches. I'm considering applying for membership there.
Green Hill is outside Conestoga. I've never been there but it has a reputation as a drinking club that allows guns.
Columbia Fish and Game limits round counts in magazines and has a rule banning silhouette targets. Not a horrible facility, but it's definitely a hunting club. I feel like they'd let you shoot an AR but they wouldn't be happy about it.
Southern Lancaster Farmers Sportsmen's Association has steel matches that I go to sometimes. I don't know much about their rules and how they feel about black rifles.
New Holland Rifle and Pistol Club is a nice place. They had a 600y rifle range the last time I was there. It might be longer now, I had heard they were trying to expand it. Expensive.
Heidelberg Sportsmen's Association is above Brickerville. They do monthly 3 gun matches there. Not a member, but would join if it was a little closer for me. 200y rifle, small pistol area. Guests allowed last I knew.
That's about all I have experience with. Good luck.
ETA: I bounced over to HTF to ask the same question.
Also, ironically enough, I'm going shooting at trop for the first time in a couple weeks. The thought of renting an indoor land and punching holes in paper sounds really boring to me but I'm going with a newbie and have nowhere else to take them!
