I've posted the HRSA Range Rules to clarify any potential misconceptions about the range or its use.  This facility is leased from the State of Connecticut so some rules (like exploding targets) are stipulated in the lease.  Generally, if you demonstrate the safe handling and use of your firearm, the range officers will not be a problem.  While some RSOs may be a bit tougher, the rules are posted for consistent application no matter which RSOs are on duty.  All in all, I think you'd be hard pressed to find a better deal, unless you own land and can freely shoot on your own property.

When members of the public arrive with coffee, bring enough for the Range Officers

Those are pretty much a carbon copy of the rules for a ranghe in pittsburgh I used to go too, the only exception are that you charge but DO allow steel targets.  A trade off that is very much welcome in my eyes.  I'll pay to use a quality range.

Anyway, it sound like a blast to me.  One of these weekeneds I'll stray away from work and get up there.

Thanks for the post though, I really doubt I could find a better range.  Also, I'm glad to see I can pattern my shotgun there.  Can you patterns with both birdshot and buck shot there?  or just birdshot?  Also, are do these rules also apply for the range in Naugatuck?

Yes, these are the rules for the range in Naugatuck.  Patterning is typically allowed as the spring/fall hunting seasons approach.  We like to see the bird targets centered on the cardboard so as not to blow the wooden target frames to pieces.  Individual RSOs may be more stringent.  When I am on duty, if you are showing safe shooting behavior and are not blowing the HRSA target frames to pieces, you can pattern your gun all day.  If you want to bring your own frame and cardboard and blow it apart, that's fine, as long as you haul the debris home.  

When the range is more crowded with your neighbor's target close to yours, we tend to be more restrictive since we don't want you blowing apart your neighbor's target.  When in doubt, ASK the RSO BEFORE you shoot.  Again, as long as you're safe, you'll find most of our RSOs to be flexible.

Understandable.  Thanks for the info!

Ken - When will the rules reflect that if a member of the shooting public arrives to shoot and they are drinking coffee, they must bring enough for the ROs?  I didn't see it in the addendum.
