.30-40 and 8x56R loads with IMR-7383 powder
I developed two more loads using IMR-7383 RAD-73 surplus powder.
1896 Springfield .30-40 Krag rifle with Hornandy 168 grain FMJ National Match with Remington LR primer. 45 grains of powder. 100% case loading no unburned powder grains in the bore.
8x56R long rifle with 208 grain Privi FMJBT both LR and Berdan primers. Commercial and WWII Nazi surplus brass, both annealed at the neck and shoulder.
51.0 grains of powder. No unburned powder in the bore. This load is slightly compressed, but not to the point of a pressure spike due to it.
Both loads show no signs of pressure problems and both bolts have normal force to operate. Primers are normal looking.
I will be shooting both rounds at 500 meters this up coming Saturday and will post the results.
