Of course the first one for me would be Quigley Down under with his 45-110 Sharps with Tom Selleck. Second for me would be Winchester 73 in 44-40 staring Jimmy Stewart. Third would have to be Sargent York's 1917 303 Enfield staring Gary Cooper I should let the rest of you chime in but have to mention the Tom Horn movie with his 45-60 Winchester. I know there are many others like "Sniper" with Tom Berenger and "Shooter" with Mark Whalberg but will leave that to you.
