Ranch rifle accuracy
I have an inherited 187 Series Ranch Rifle with a factory installed 580 series 1:9 barrel. (The original 1:7 barrel was not installed square with the receiver). It's accuracy performance was on a PAR with the half dozen or so other Mini-14s I've owned over the years. After installing an Accu-Strut, Wilson Shock Buff, the next to the smallest powder bushing available, a Choate M-14 type front sight/flash suppressor, and with trigger pull reduced to 3.5 pounds by Clark's Custom Guns, I'm getting some decent groups. So far, it has a preference for Super-X 55 grain soft points. Five round groups, each on separate range days measure 1.0, 1.45, and 1.6 inches. My 64 grain handloads have grouped no smaller than 2.6 inches. Penetrator 62 grain rounds form Lake City, S&B, and PMC have ranged from 2.2 - 2.75 inches. I've added a 55 grain handload development job to my project list. The rifle currently sports a Leatherwood/Hi-Lux 1-4X30mm CMR scope in Millett Angle Loc Rings.
