If you are 'strowbridge' on Rimfire Accuracy and talking about ARA, your question has already been answered. If another sanctioning body, then go to their website and read their rules. For as long as I have been shooting sanctioned you would not believe how many questions I have seen just like or similar to yours that are answered by people who don't know what they don't know and were answered wrong! When dealing with sanctioning body rules, the sanctioning body is who you refer to, not a forum.
