Mid-Vary Powders
These powders are the workhorses of the reloading world. They provide steadiness between burn price, velocity, and stress, making them versatile sufficient for use in all kinds of cartridges. Many frequent rifle and pistol cartridges use mid-range powders.
Slowest-Burning Powders
Sometimes used for magnum cartridges and for pushing heavy bullets. These powders produce a slower, extra sustained stress curve, permitting for optimum velocity with out exceeding secure stress limits.
For instance:
.223 Remington
Powders similar to Hodgdon H335 or IMR 4198 are generally used for lighter bullets.
