I run 4.5 Titegroup 130 m&p mold projos powder coated with my .38 special
sometimes I order the conical 125grn projos from American Reloading with 4.5
but I'm gonna start with a Lee mold 158grn RNFP powder coat with 4.2 Titegroup and will crono and share the results..
4.5 TG 130 cast projos shoot at 870 FPS very comfortable load to shoot and fun! No flat primers and shooting through a snub nose colt king cobra
