I found this page helpful when I went through the process for my license so I figured I would post my recent experience for others. I know some of this will be a repeat.
In mid October 2012, I took the basic firearms course. Shortly there after I called the licensing office to set up my interview. They were 8+ weeks behind and the earliest they had available was December 31. I went in to BPD HQ early and filled the application. Yes the City of Boston has there own forms, not the states forms. The only forms you need to bring are you BFS completion cert, birth cert, drivers license, and $100 cash only. I was asked when was best for me to take the Moon island test and gave me a list of dates available. I chose the soonest which was January 2 and was given a range pass. After that I was fingerprinted and brought out back where they basically just ask you all your personal info over again and photograph you. I wasn't asked why I wanted firearm or any of that. Sport and target was filled in already. Although no longer required, I brought in some letters of recommendation and a letter about why I wanted an LTC, etc. What I had brought in wasn't even look over and was said it would be passed on. The licensing officer said it would be about 10 - 12 weeks before I received my license in the mail.
On the morning of the range test I tried to get there early but drove by the place and got stuck in traffic after I realized it and turned around (its also a bus route and they only let one bus at a time drive over the bridge so you have to sit and wait). I ended up being a few minutes late but they didn't care or say anything about it. We even waited about another ten minutes for someone else to show up but never did. There was one of other tester and myself. About half a dozen officers were inside and they were all nice people. They were asking about what I did for work and about restaurants in my neighborhood. One officer told me at the end of the test that he asked what I had done for work because I hadnt realized I went in there with my knife clipped onto my pocket. We pick up our buckets that have or Ruger revolvers, ammo, ears, eyes and head out to the range. It was 7 am, 15 degrees, and the sun was barely up. Gloves are not allowed while shooting. Targets are larger than I expected. We shot 30 rounds total. We shot 12 rounds double action two handed from 7 yards, then backed up to 21 yards and had the option to shoot DA or SA, one hand or two. They recommended a nice firm two hand grip and single action. So thats what I went with. It seemed like the instructors wanted everyone to pass, as there were helping out and giving tips to us as we were shooting. Each round is worth 10 pts and you must get at least 210 of 300 to pass. It was my first time shooting since taking the BFS back in October. Happy to say I scored extremely well and all the officers personally complemented my shooting, the sergeant even come out of his office to commend me. It was nice considering some stories Ive heard here about them being rude. They told me it would take 8 - 10 weeks for my license.
So now its been about 2 months and I am still waiting on my license.
Hope this helps at all. Any questions just ask.
