Well, my "Haven't pulled a trigger for 50+ years" record has come to an end with a bang.
A late Father's Day present from my daughter had me firing the four-inch deck gun on the HMCS Haida in Hamilton Harbour.
Thanks to it being a low charge blank, the Burlington Sailing and Boating Club sustained no direct hits. However, there might have been a bit more seagull poop at the time of discharge.
The presentation was very interesting, covering the history of the ship as well and the intricacies of the mechanisms.
