Some damn good shooting here guys so hopefully David will provide more commentary...
Freedom Arms M83 with .45 ACP cylinder, 5-shot 3.9" group @ 100 yards. Unlike the .454 and .45 Colt cylinders, which have tight chamber-to-bore alignment, this factory original .45 ACP cylinder measures .007" chamber/bore offset on all five.
M83 .45 ACP load: Remington Golden Saber 230 JHP; 8.5/Accurate #5; Fed 150 GM; Fed brass. COL=1.240". V=925 fps. Sandbag 100 yds.
M83 4-3/4" .454 Casull with .45 ACP cylinder. 5-shots=2.3", with 4-shots in 1.1-inch. Sandbag, 50 yds.As throats are firm and forcing cone very short, .007-inch chamber offset is not too hard on accuracy.
FA M83 4-3'4" with .45 ACP cylinder, groups fired at 50 & 100 yards
Jim Stroh modified M83 .44 Mag to my specifications, including special tool grade stainless oversize swivel stud to replace front grip frame screw. Load: Sierra 240 JHC; 23.4/H110; Fed 155 GM; Starline brass. COL=1.592"-1.596". V=1580-1600 fps. Redding carbide dies with
FA Casull M83 .44 mag; Shilen 10-inch, 1:16" twist; Leupold 2.5-8x34mm IER scope with dot reticle and target turrets; Leupold rings. 3-shots
Wind from 8 to 10 o'clock forced me to crank 30-clicks left windage. Held dot center of shoulder with vertical crosshair on front leg. Elevation
Wind easily bends a revolver bullet at long range, despite seemingly fast time of flight. Rested revolver on rolled nylon belting. Three shots=5.8
