So I chrono'd again this past weekend. 5.4 grn of n320 = 170 pf in my edge. My buddy also fired 5 of my rounds out of his edge, and averaged a pf of 177.
My gun has less then 500 rnds through it, so I am not sure if I should think about getting a new barrel or wait and see if this one will break in or something. Thoughts/experiences?
