Finally got the SS up and running and am currently breaking in the barrel. I did shoot a couple of groups and need to do a lot of playing yet but started with a couple of loads I thought might work. It looks like it has some potential! My chrono is on the fritz but based on "Bigngreens" testing, I estimate these loads at over 3100'. The rifle is a joy to shoot and feels different than the 6.5 Sherman? More of a push than a punch I would say.
