The .22 is dead on at 50 yards and this afternoons shot was no more than 30. The groundhog had been moving toward me eating grass and I got him high in the chest. He managed to roll and fall back into the burrow. Iv'e gotten maybe a dozen this year and this is the second that got back to the burrow. I need more knockdown power. I'm not much of a fan of the .22 mag, but I'm ready to start using a .22 centerfire. I'm thinking a .223 or possibly the .204. Some of you think very highly of the .204, please tell me about it. I'm open for suggestions-------John R
