Widener’s Reloading & Shooting Supply recently published a helpful introduction to reloading powders. Widener’s online Guide to Smokeless Powders shows the various types of powders, and explains how the differences in powder kernel/flake size and shape, and burn rate affect performance. We recommend you visit Widener’s website and read the Powder Guide in full.
Take a close look at these illustrations which show the key differences between the four main powder types: extruded (stick) powder, ball (spherical) powder, flattened ball powder, and flake powder.
Burn Rate Basics
Widener’s Guide to Smokeless Powders also has a useful discussion of Burn Rate (a confusing topic for many hand-loaders). Wideners explains: “While a gun powder explosion in the cartridge seems instantaneous, if you slow it down you will actually find that each powder has a different ‘burn rate’, or speed at which it ignites.” This video shows powders with two very different burn rates. Watch closely.
Different burn rates suit different cartridge types notes Widener’s: “In general a fast-burning powder is used for light bullets and low-speed pistols and shotguns. Medium-rate powders are used for magnum pistols, while high-velocity, large bore rifle cartridges will need slow powders[.]
It should be noted that burn rate does not have a standardized unit of measurement. In fact, burn rate is really only discussed in comparison to other powders; there is no universal yardstick. Specifics will change by cartridge and bullet types[.]”

Praslick Wind Reading Class at 2021 Precision Expo
This year wind wizard Emil Praslick will lead a class on wind reading. Praslick is one of the foremost authorities on wind reading in the world. The former USAMU Head Coach has represented the USA in international long-range shooting for over 20 years and has developed training strategies for both tactical and competitive shooting. Praslick’s wind reading class will help shooters gain insight into understanding the mechanism of wind drift and its influence on bullet trajectory, techniques for recognizing and determining wind speed and direction, and strategies of wind management and target engagement. The daily classes will be held at 10 am and 2 pm on Saturday, and 10:30 am and 1 pm on Sunday.
WIND WISDOM: Determining the Direction of the Wind
Praslick noted: “The Precision Rifle Expo is a fantastic opportunity for both industry folks and the public to meet and learn about what’s new in the precision shooting world. It’s also unique in that the organizers present instructional content for the attendees. I’m really looking forward to teaching and talking to people about the techniques, strategy, and some tips to shooting in the wind. We’re once again partnering with Vortex, who is providing optics for the students[.]”
