Kidd rifles shoot 1/2 at 50 yds. On the other hand Shilen are used in many benchrest 22 rifles. Cant go wrong with either but Im thinking Shilen might be slightly more accurate. I have a few Shilen centerfire barrels.
Kidd. Heavy match. kind of a crap shoot, I just saw a federson barrel that shot lights out. Have a savage tr that I cut down that shoots lights out as well. But all of my kidd barrels are shooters.
