I entered the marlin 38-55 world a few months back. Why did I take so long? I have been trying to get a good 200 yard load for our monthly buffalo shoot. The best so far is 15.3 grains of 4759 and a 250 lee bullet. With tang sight and a 17 lyman front, I have managed to stay in the 3" range at 200. I am up against 12 pound sharps with sights that run about what I paid for the Marlin. Any of you guys have some tips to share? Any help is appreciated. ???
