I "favor" which ever one I feel like using that day. The one (beyond any doubt) that I have killed the most deer with is a Mauser in 270 which is now on it's 3rd barrel. It was the first rifle I ever built and I did it when I was 12-13. But it's not a lot of fun to kill deer with it anymore because it's just too easy. For the last 25 years or so, the rifles I prefer to use are all iron sighted and many times it's a flintlock in 62 cal.
and also my Ruger #1 in 9.3X74R some. (no pic of that rifle) In addition to these I have killed a number of deer with my Remington Pump 35 Rem M141 and my two 300 Savage rifles, a 99 Savage and also a Remington M81. (No pics of them either) I just enjoy hunting with old fashioned rifles and where I live my seasons are long and deer are usually plentiful so I have no disappointment in the times I go out and don't get to shoot one. My average of deer killed per hunt us over 50% so I am doing just fine with the old fashioned guns.
