This is a western rock-chuck or yellow bellied marmot shot at 315 yards with a 6mm AI.

After working up a load that would get 85% hits on a pop can size target at 500 meters I was ready to go.

I hope to get a smaller 6mm soon that might give me better long range results on targets but I will still use to Ackley for varmints.
