With the hunting seasons about done for this year, I was thinking tonight about past hunts and the guns I have used. Although shot placement accounts for most instant kills, some guns have done it more that others for me. How about you? I think its about a tossup between my 6.5x55 with 140 Grain Hornady inter locks and my 308's. For all big game animals of all sizes, these two rifles have furnished the more instant kills than any others. This would include my 30-06 and a basket full of Magnum rifles. Why would this be? I think I shoot those rifles better than others and both calibers are very dependable and I have confidence in them. This to me makes a rifle much better than it might show on paper and charts. Plus both rifles fire bullets that will penetrate to the vitals of most any game animal. I quess to me that makes them the best gun for the job.
