So I just recently finished this XP up. It is a 221 fireball and I was using Remington factory ammo with the 50 grain bullet. I haven't shot any groundhogs in a long time. Seems like the coyotes have thinned them out a lot from what they used to be. The shot was a little over 100 yards so nothing really special there. What made this so special to me was I had my youngest child with me. He is almost 5 years old and he was a great hunting partner on his first groundhog hunt. When I shot and he saw it was down he was so excited. He wanted to carry it and had to show it to his papa, my dad. Sure made for an awesome Father's day! It doesn't take a wall hanger or big money to make great memories with the children. They can have fun catching a bluegill or shooting a whistle pig and so can we! I have always loved to hunt, fish and shoot but I declare I have had more fun watching my younguns over the years than any other succeses I have had in the outdoors.
