Red_eagle,
Looking forward to seeing your reports on the new barrel, but I can't help but wonder: Why in the heck did you go with a FP bullet, out of an Encore barrel?? One of the real benefits to loading your own 30/30 rounds from a Contender, Encore, or any other single-shot, is you can choose a pointed bullet for better long-range performance.
Anyway, be sure to let us know what she does, at the range.
