I used to shoot with a group that held woodchuck matches, similar to what you are talking about - but they were brown, full sized woodchuck targets - head shots didn't count - only the rings on the tummy counted.
Bullet holes that touched a line gave the LOWER of the two counts. Opposite of normal scoring
All rifles were to have round bottomed stocks - no flatter than a Rangemaster or a Marksman, and shot from Harris or Parker Hale style bipods, "X" sticks, or off a back pack on the ground, with a squishable rear bean bag. No shooting tables, all shots were prone or sitting. Calibres were 243 bore or smaller. Maximum scope was 24X.
No flags, no "range crap"... no nothing that you wouldn't find in a field on a farm, (cuz the match was held in a field on a farm)
Three classes:
Factory (Rem VS's and Win HBV's, Sako L46's and L146's, etc. type rifles) - must be factory stock, trigger work or replacement was OK, (any trigger) and glass bedding was allowed. Must be the original factory calibre, no barrel setbacks, Ackleys, or rechambers. Max weight was 12.5 pounds, with scope and bipod. US commonly available factory cartridges only.
Semi-custom (40XBs, Coopers, Sako PPCs, etc) same rules as above. Must be factory stock, trigger change and glass bedding was allowed. Max weight was 15 pounds, with scope and bipod.
Full custom - field stocks, anything-any cartridge - max weight with bipod and scope was 15 pounds.
... no benchrest rifles, and no benchrest rifles with a round piece taped to the fore end - all gamers were stopped at registration. It had to be a REAL woodchuck rifle.
You could enter alone, or team (ranger/spotter), using hand held bins only... or as a single shooter.
No "Spotting" shots, you were "on record" for the first shot.
There were two shots per target. The second shot had to be fired within 10 seconds of the first, or it didn't count - if only one shot hit the target, it was worth 1/2 of the ring score.
The
LOWEST shot counted (ouch!!)
The rules were designed to keep out the gamers.
Targets were numbered and positions were numbered - you drew tags for two numbers for position and targets - if you got 3 and a 12, you shot from position 3, and shot all targets numbered 12... yup, it was not fair.
Targets might be partially hidden cuz they were set up in a dip (peekie woodchucks) with only their head showing behind a rise... and often weeds in the way (made lasers hard to use)... but you still had to hit them in the tummy.
After the third match, a lot of Wild, Barr & Stroud, and Swedish Periscopes showed up, cuz people found out just how unreliable lasers are against woodchucks. The lasers were NOT reliable.
It was the most fun I have ever had at any match... no one got away being the group "Big shot" cuz next time he would get his clock cleaned by some kid.
There was a lot of teasing, and you brought your own lunch - it was an all day affair.
