Open 60 shots; women, 40 shots. B40/4 targets (10 meters). Total time for 60 shots including unlimited sighters is 1 hour 45 minutes. For women, 40 shots in 1 hour 15 minutes. Three shots per bull. Fired as a 17 1/2 minute sighter period, then five series of 12 shots in 17 1/2 minutes. All sighter shots are fired before the first record shot.
Also, if anyone has shot one of these matches before I'm curious as to how the range is set up. Specifically, are the targets on a return system, or do I have to walk out to hang a new target after every 12 shots? And if that's the case, do they call a cease fire on the entire range so everyone can switch out targets at the same time? That seems kind of.... silly? What if one shooter takes twice as long to shoot his 12 shots compared to the 'fastest' shooter on the line?
I've shot these in local clubs, sorry to say that they hang sometimes at the incorrect height, but the rules do have some height recommendations. When we shot them we would use a set time IIRC 15 minutes for sighters and 17 minutes for record. When all shooters were done within the allotted time we would walk foreword and change targets. At another club they had an electric retrieval system and shooters took charge of changing targets, trying not to change when a neighbor was " on point". I may have the times wrong since I am going by memory they may be FP times.
I shoot these at home and have shot them in different ranges. At home, I set the TOP bulls at the required 55" for ISSF rules. I then shoot 2 bulls, walk down and flip the target and repeat.
At ranges with carriers, I do the same (we drew a line on the carriers to indicate the correct level at my last club) ~ shoot the top 2, bring in, flip, send out and repeat.
On ranges where you have to walk down-range to change targets, I tend to split the difference and put 2 targets slightly higher and 2 slightly lower. I *HATE* doing this as it's not what I train, but you shoot what's available.
