Hi Mike:
That Weaver 6-20X scope will work fine in our Factory Sporter class. The rules allow up to 24 power in Factory Sporter. But: If you have a scope with more than 24X, and it is variable, you are allowed to use it, as long as the power selector ring is set at no more than 24X and the ring is taped so it cannot be moved.
Here is information on the rules we use UP here at Sault Ste. Marie. They are the same as the rules used by Rimfire Central in their On-Line Matches.
Seven years ago we started Unlimited BR Matches on Rimfire Central. (Same rules as ARA, but using the USBR target) Our course of fire includes both 25 & 50 yards on that same USBR target.
Four years ago, to encourage more shooters to get "Into the Game" we set up a class we call the "Factory Sporter Class" We shoot under the RFC On-Line Match rules at our club UP here at Sault Ste. Marie. There is also a club in Florida, one in Pennsylvania, one in New Mexico, two in Texas and one in Rio de janeiro, Brazil that shoot with us.
In the past we have had clubs from California, Massachusetts, South Dakota, Utah, Washington State and New York at one time or another. There are also about 100 individuals around the country that shoot on their home ranges and report scores in the RFC "Matches" section. Most of our shooters are not near ranges that run sanctioned matches. They shoot alone on their home ranges, and are allowed to score there own targets "Under the Honor System". I have names of about 40 shooters who have moved up to Sanctioned matches after getting a starting in the RFC On-Line matches.
