Flyswatter Challenge

Just occurred to me to clarify. Does the time spent shooting fighters count towards the 5 minutes to complete the shoot.
Time starts when shooting at the first sighter and is included in the 5 minute time limit.

I wouldn’t follow that 5 minute rule since almost all competitions require a minimum of 20 minutes for 25 targets including the sighters.
 
Well have had another couple of goes at my club at 25 mtrs. I improved by 1 to a score of 15. I was far more erratic though, it was either spot on or way out, I was lucky to keep a couple in the circle. At home over 15 yards I did 17, not good but I switched to my Brocock Commander XR and hadn't zeroed it properly. I was wondering if you are allowed to support the butt of the rifle. I don't and just use a front rest as I do a couple of club comps and rear support is not allowed.
