Well, He finally did it.... He broke the 500 yard mark. We've been trying for two years to get him to shoot a groundhog past 500 yards, and yesterday my 81 year old Dad killed one at 538 yards. We headed up north to do a little groundhog hunting before the fields get too high. Philny1 met up with us and we fought the cold, windy day to find some groundhogs. I had my .240 Wby and my .284 Baer along. We all shot a few with each rifle throught the day. We found one at 538 yards in the 20mph wind, and put Dad behind the .284 Baer. It's extremely accurate, spitting 180 gr Berger's just under 3100 fps. One shot and it was all over. Phil and I set out to reclaim his trophy, and had to get his mug shot. Now we need to get him one at 1K..
