The new spring is in, don't know how to tell the pounds, Armscor did not mark it so I assume it the 16#, I can tell it's a lot heavier and it was a lot longer, about 3/4".
I did order a 18.5 and 20lb wolff springs and new MSH, should be here next week. need to make up some rounds to test out!
Spent brass to me is like the ring to Gollum "We wants it, we needs it. Must have the precious"
