Questions - 22RF F-Class

Ok, I'll try to be un-technical, How do you determine the correct weight of a rifle? from my experience a scale that weighs 8 lbs accurately is likely to be too small to properly hold a rifle.

Are these matches being recognized and sanctioned by NRA or whoever? Or are they still "Simulated F-class"?
If someone is actually tracking scores I would be tempted to make my old Glenfield model 65 a sporter class rifle, assumeing you will allow someone to shoot two guns in a match.

It probably wouldn't matter that much if it were just fun, games, and self improvement.

It's all fun and games for me, technical or not.
But I do try to do things right.

So if we have few enough people that we can all shoot at once there is no second relay and no second gun.

Basically, the more people we get, the more guns we get.

If we had a situation where a person wanted his son to shoot the same gun as he is shooting, they would require a spot on the second relay. We would not want to leave the son out.

Only after everyone else has thier first shot would I want to get a second gun into the match.

Someone will have to make judgment calls on a case by case bassis and the shooters will be gracious enough to support the judgment of the MD.
