There are a couple of different sets of rules, but here are rules from the majors:

Superstition Mountain Mystery 3-Gun

Rocky Mountain 3-Gun

Fort Benning/Fallen Bretheren 3-Gun Challenge

USPSA Multigun and Individual Gun Rules

Lastly, here's a decent site to check out: 3 Gun Rules.com

Some of the best shoots that I have been to, use IPSC rules with IDPA scoreing

I'm partial to IMGA rules.

Simple and straight forward.

I've always disliked adding a time penalty for missing a target or hitting a no-shoot. It seems so minor a penalty for such a major mistake.

After much discussion, the local match did away with the old scoring system that has it roots in speed pistol and went to a "practical rifle" format.

One point for each target neutralized and your time to your determine place.

It looks something like this for a ten target stage:

Points____Time_______Rank
10_______32.25________1
10_______41.95________2
10_______58.52________3
9________20.29________4
9________45.85________5
8________15.78________6
8________37.25________7


So there is no advantage to skip a target and take the penalty because your score will drop below everyone who hit all their targets. And if you hit a no-shoot you get a minus one.

It's simple and elegant.

I spoke too simply before. Some stages are one point more complicated.

The most complicated it's gotten is an occasional A-zone worth one point, the rest zero, or an A-zone worth two points and the rest one point. Also, if two hits are required on a target than each hit is worth one point, for a total of two points per target.

I haven't seen the scoring system on paper, but it could probably fit on less than one page.

Penalties, depending on severity, will either be a minus one point or a time penalty. At no time will a missed target be assessed a time penalty. A missed target is too critical an error to be extrapolated to a time value.

With the limited number of paper targets it's been no problem and it will be the same for all paper targets on a stage. Steel targets with a flasher are pretty obvious as well. It's simple.

The object of a shooting match should be hitting the target and not hitting no-shoots. Fastest time wins. Think of it like an NRA High Power match or a military rifle qualification range where shooters are scored on both their hits and their times. We've eliminated the 3-10 second penalties that civilian based matches of the last 30 years somehow thought sufficed as penalties for missed targets or negligently shot no-shoots.

Umm actually it works very well and I use that exact same set up in the three gun matches I host. It places an added emphasis on accuracy over hit factor scoring. You don't have to worry about failures to engage because you have the fail to netralize rule which stings more and is easier to score as an RO. Its easier to add up the stages without a calculator. I have used USPSA scoring and IDPA scoring and much prefer the IDPA scoring. Plus you don't have to worry about major minor. I don't like the rules where you get 2 any where on paper because that places no emphasis on accuracy outside of just hitting the target somewhere.

What rules does the Rockcastle Pro/Am go by?
