Went out to the farm today to shoot at my gongs. I brought my 6.5 Creedmoor for some fun time 1000yd shooting. Later I set up a paper target to get some tight groups at 600 yds. Letting the CM cool down I grabbed the 204 and nailed a 10" gong easily for 10 rounds. To my surprise the AR 500 was moon cratering from the 204! The round was 3900 fps 39gr smk. The CM never scratched it. Oh yea-a Rock Chuck blew up from a smk also. He should not have made home at the range
