Welcome to the site where the owners and members have had it with playing "nice" and being "inclusive" and "tolerant" of points of view that are destroying the fabric of what made this country great. The members here are sick and tired of politicians of all parties lying, deceiving, stealing, and pretending they are doing it all for the good of the country while selling out to special interests who have the set goal of destroying this country. We have had enough of career politicians who use their office only for personal gain, and who refuse to listen to the people who put them in office. The membership is no longer part of the silent majority who play nice and get along while getting screwed by anyone with a loud voice and an agenda. We will no longer allow anyone to piss down our back and tell us it's raining. And we like guns too.

gun Vihtavuori Explains Powder Grain Shapes

POWDER GRAIN SHAPES — What You Need to Know

The shape of powder grains has a profound effect on the performance of the powder charge, as it concerns both pressure and velocity. There are multiple powder shapes including flake, ball, and extruded or “stick” (both solid and perforated).
Interesting article.

Having reloaded for over 45 years I've never been a big fan of extruded stick powders, I use spherical ball powders for rifles and flake powder for .357 Mag pistol.

Thumbs up Interesting article.

My Nam buddy Fred worked as a fireman for 25 yrs up in Perry Florida 'Saint Marks' at the powder factory and told me they make extruded powder.
They sell all over the world. Hell that Russian ammo we buy might come from their? Up until a few years back if you bought their powder you were firing WWII surplus powder.
Mixed in water then shipped by rail from storage out west. Refurbished at St. Marks then off to us. Guess who owned the storage facility and got rent from Uncle Sugar since WWII??
Lady Bird Lyndon's wife. How convenient. $$$
