I just posted some information over on the .22 Rimfire Forum about State Team Matches that are being held on Rimfire Central. Any rimfire rifle. No limit on scope power. Trigger many be light, but must be safe.
Shoot off sandbags, or if you want: Shoot prone, over a log or over the hood of your pickup.
25 yard and 50 yard matches on the United States BenchRest (USBR) target.
The .22 Magnums and .17 HMRs are not allowed in the 25 yard matches, but may shoot in the 50 yard matches right along with the .22 RF rifles.
