Hogdon Reloading recommends between 3.5 and 4.0 grains of 700-X powder for a 100-grain, 9-millimeter projectile and 5.4 to 6.0 grains for a 155-grain projectile in .45 ACP. For data on other bullet weights and loads, an interactive reloading data tool is available on the Hogdon Reloading website.
Hi-Skor 700-X is a smokeless extruded flake style powder manufactured by IMR in Valleyfield, Canada. It was introduced in 1963 as a light field shotgun load and target pistol load. Hogdon Reloading purchased IMR Powders in 2003, but the IMR products retain the original branding and manufacturing process.
Never exceed the manufacturer's recommended loading data. Always start with the minimum specified load. After each firing, check the primer in spent cartridges for signs of excessive pressure. If the edge of the primer is completely flat, the maximum safe load for that particular firearm has been reached. Somewhere between the minimum and maximum safe load is the ideal amount for accuracy.
The National Rifle Association warns that pressure caused by excessive loads could severely damage a firearm and cause serious injury or death to the user. Modern smokeless powders are substantially more powerful than traditional black powder, and the two should never be substituted or mixed. Always keep powders and primers away from heat, sparks and naked flame.
