I know that there are a lot of doubters and naysayers on here concerning the .40 as a deer caliber. Let me tell you after witnessing first hand a couple of the deer that Allen has killed with his .40, and one that a former co-worker killed with his, I am a believer. That ball may be small but the effects that it has on a deer is devestating. Then to sweeten the pot, if no deer are moving you can start busting bushytails out of the trees with the same rifle. I will have one soon.
