I think a lot of how well a club does is due to who is running it and how it is run. Then sometimes I think it doesn't matter that much. Occasionally there are personal issues between shooters and match directors that will cause some folks to quit shooting.
Rules are important but not at the cost of not shooting.
Example. Husband and wife show up and the MD tells them that he cannot load the pistol for her. (new shooters or perhaps elderly but not necessarily physically challanged) Guess what? they will not be back. If they are excellent shooters and have been in the game for a long time then they will understand that they must play strictly by the rules. For the new or not super serious shooters, I say let them shoot and encourage them to have fun and invite their friends.
Also do not require people to join IHMSA after 5 matches or whatever. Let them shoot and when they are ready they will join, or not, every person that comes out to shoot is an asset to the club, IHMSA, the NRA and our shooting way of life. We should encourage them as much as possible.
We cannot tolerate, safety violations, reckless or obnoxious behavior, cheating or anything that will cause disruptions to other shooters.
Let new shooters shoot 22's at FP targets, they will hit more and will be more likely to come back.
Full shooting range, open houses (with demonstrations and participation.) help as do free silhouette day's.
The thing that really keeps a club going is word of mouth, by every shooter in the club. One person (match director) cannot do it all, it requires everyone to tell every person they can and that will listen about silhouette shooting and how much fun it is.
To be successful it requires a group effort.
