Widener's Reloading Smokeless Powder propellant Guide

Widener’s Reloading &amp Shooting Provide not too long ago published a valuable introduction to reloading powders. Widener’s on the net Guide to Smokeless Powders shows the different varieties of powders, and explains how the variations in powder kernel/flake size and shape, and burn price impact efficiency. We suggest you pay a visit to Widener’s site and study the Powder Guide in complete.

Burn Price Fundamentals

Widener’s Guide to Smokeless Powders also has a valuable discussion of Burn Price (a confusing subject for lots of hand-loaders). Wideners explains: “While a gun powder explosion in the cartridge appears instantaneous, if you slow it down you will essentially discover that each and every powder has a distinct ‘burn rate’, or speed at which it ignites.” This video shows powders with two incredibly distinct burn prices. Watch closely.

Unique burn prices suit distinct cartridge varieties notes Widener’s: “In basic a quickly-burning powder is utilised for light bullets and low-speed pistols and shotguns. Medium-price powders are utilised for magnum pistols, when higher-velocity, significant bore rifle cartridges will have to have slow powders[.]

It must be noted that burn price does not have a standardized unit of measurement. In reality, burn price is definitely only discussed in comparison to other powders there is no universal yardstick. Specifics will alter by cartridge and bullet varieties[.]”
