Not a sarcastic question. I used to shoot HBR score and 6PPC group matches...mostly locally. For various reasons, I stopped shooting my rifles entirely and lost touch with the sport. Now over ten years later, I'm thinking about doing some shooting. My equipment, including bench guns, scopes, rests, bags, reloading items and components are all at least 12-15 years old. Not looking to be competitive, but don't want to be embarrassed either. What sort of changes have been happening? What's most significant?
