I am a member at Highrock, it's near waterbury, about an hour from old saybrook. Its a real safe/clean friendly place if I do say so myself. albeit quite crowded on any given weekend. If i wasn't workin this weekend Id invite you up for an early session before they open to the public at 9am. Come to think of it,... are you going to be around anytime the next week? I am off Tuesday and Thursday and could be persuaded to do some midweek plinking.
The only other real option is "Ye ole" Blue Trail in Wallingford. they are back open and have a very well stocked range store.
you might try hoffman's new indoor range on the berlin tnpke. hartford. Call first as i am sure there are probably quite a few restrictions. Nice poiint is they let you rent guns to try out. Could be fun to fondle a few you might never think bout buyin without tryin.
there is also an indoor range somewhere round guilford, I forget the name. I heard bout them from some guys at a plate shoot at the newhaven sportsmans club but I hav enever been there myself.
