Key word being Favorite? Easy answer for me, one my 30-30's! My Marlins 336 killed the most, but my Mod 64 Win has become my favorite by far! But I've got a new-old 94 that's doing well to gain first place. Where I hunt, mountains which equal 99% inside 75 yd shots, and most those inside 40yds, a Lever 30-30 & iron sights is hard to beat!
Now best all-around, my 30-06!
