Just got back from the R-100 shoot in North Royalton. I've been shooting 3-d for about 25 years and this was the most fun I've ever had at a 3-d range. We shot 100 different targets and had a blast. Two of us in our group of four shoot the Cardiac and when we left both of us were in the top 15 overall. They said they had over 400 shooters for the weekend. If you get a chance to attend one of these shoots I'd highly recommend you go.
