All the little things add up, they really do. What are you using a 1891 or 1909? I got a (get this) 1909 that has a brand new barrel on it. I about fell over when I seen it. The grooves are .3110000 Can't ask for more then that in a 7.65. I find a major difference in throats and bore dimension between the 91's and 09's, what do you think?
