I used a 30-30 for all of my deer hunting from 1958 to the mid '70s, that is when I was getting ready to go on a trophy Mule deer hunt up in Arizona, and a good buddy talked me into getting a .270, as most of the shots on trophy deer would be at 250-300+ yards. Well to make a long story short, I did get a trophy 6 point, 250# buck, but at 75 yards at the most. Later that year I got an elk fork horn at a little over 100 yards, again with the .270. You might note that either of those animals could have been taken with my 30-30.
