Actually, I don't use SR 4759, but I do load Blue Dot with a 100 gr Remington Core-Lokt. Using 18.2 gr, a gong at 245 yards can be hit with boring regularity. The load also accounted for three deer this past season. #1 grandson got a nice 8 point and the neighbor's granddaughter shot two with the same load out of a 22" Handi Rifle.
I normally deburr the flash hole and neck size with a Lee collet die. The load will shoot 1 1/4" or better at 100 yards.
People have their doubts about these reduced loads, but here's a 3 shot 100 yard group shot by #1 son out of a 1965 M600 18.5" barrel in 6mm Rem.
