If a handloader dreams a certain muzzle velocity, the reduction is instantly proportional to the accurate 5744 reduction in powder charge: lower a full-power demand 25 p.c, and muzzle velocity drops twenty five percent. Velocity math with double-dependent powders for instance Accurate 5744 isn’t quite as exact, but it gets a handloader while in the ballpark.

The perfect-cartridge trend carries on these days, but social improvements have revived minimized handloads, which includes Obama’s election and reelection.
