Load data for 300 RUM



Does anybody have any data or experience with the 150 gr. Scirocco or the 190 gr. SMK in the 300 RUM ? I have one built with an old but in good condition Kreiger Palma barrel that has a 1 in 13" twist and is 28" long. With 165gr. Hornady BTSP's it will shoot 1/2 moa to 600yds. I am looking for a better constructed bullet for more weight retention. At 300 yds into wet newspapers the Hornadys retained about 40% of its weight, velocity was 3435 fps average. Any and all help is appreciated, Wayne.
