"Was considering ER Shaw barrels (have a call into them now),Not the greatest but good enough for a
couple of beat up old parts rifles."
Rod, why invest in "a couple of beat up...rifles" before trying them "as is," and after a thorough bbl. cleaning of course? Also, would you consider looking for a "new" Civil Guard (i.e., little used) M 28/30 or M 39 Finnish Nagant: Very accurate CB shooters;(Sako, Tikka, Valmet) + their front sights are easily adjusted for windage. The CB of choice is either Lyman #314299 or the NOE #316299 if the bore is "generous."
