Hi guys. I obtained an M1 through the CMP and could not be happier with it. I highly recommend the CMP for anyone, especially for getting more young shooters into the sport. Anyway, I used to think I couldn't see 600 yards, let alone compete with open sights at 600, but I'm finding that my eye focuses great when looking through a 50 thousandth-inch hole. So I've been hitting a 1-foot square steel plate at 300 yards pretty regularly, and now have some official targets I will be taking to the range, but I only have access to 300 yards. Where I will be competing does have a 600 yard firing point, and I will have never shot at that distance before. I get two sighter shots, so... Roughly how many clicks (standard sights) more than the setting for 300 will get me at least on the paper at 600? I know ammunition will make a big difference, and I will probably use S&B or that Greek Olympic 150gr for my first match (because I'm poor...ok cheap) and am shooting M2 ball surplus for practice. What do you guys do at these matches?
