My buddy has one of these calibre guns for sale. I checked the gun out today, and it's good shape. He told me that there maybe other grains for this calibre. He has boxes of .125 grain, would be an excellent varmint gun also for wolf. Packs of wolfes have moved into some of hunting areas and must be pushed away or eliminated. I know the .125 grain will take down a wolf, but my main question is will this gun with a heavier grain take down a white tail deer? Does this calibre have other grains? P.S. I'll tell you short and funny story about the gun. My buddy moved into town today, to a basement apartment. I was sighting up his gun when I focused out I noticed a huge doe whitetail standing right in front of his window. I wouldn't have had too move or adjust my aim at all, it was a perfect kill shot. I don't know if this was some sort of sign to buy this gun.
