The "latest" is that I have shot the early Sauer driller with the donated loaded ammunition at 50 yards and got a three shot 2" group at center with one forth shot flyer attributed to a 15 pound or more right barrel trigger, which I will try to correct. I cleaned the rifle barrel and came out with a very shiny, heavily rifled 11 MM barrel, after 120 years of shooting and apparently no abuse. A friend refinished and recheckered the wood wit astounding results. A great $250 investment thanks to a friend.
