Since I started shooting revolvers 46 years ago I always did the spin test after I put a moon in or after loading the cylinder.
Well there will not be 47 years of doing that as when I was performing one I am not sure if I dropped the hammer(no spur) or pulled the trigger just a little to far.
Long story short, AD and I went home embarrassed as hell. To make matters worse I went the following week to the club I usually shoot at and my DQ preceded me and I got a lot of well deserved ribbing.
The worst thing about this is that I always check my moons in the cylinder the day before any match and check for high primers at that time and I have never had a problem. I did the spin test because I saw others do it and the sound was cool. Well I am not going to be cool anymore.
