[QUOTE="bigedp51, post: 1780300, member: 28965"] Reloader 26 is a double base powder containing nitroglycerin and will have more deterrent coatings than single base powders. Meaning double base powders are harder to ignite than single base powders. I'm old fashioned the older reloading manuals always used a magnum primer with double base powders. Lake City uses magnum type primers with its 5.56 and 7.62 ammunition. And you use magnum primers with slow burning double base powders in the .357, .44 magnum, etc. And these pistol cases have far less volume than a 30-06 case. When I load double base powders I always think of the Doors song " Light my Fire" and magnum primers. [B]CHOOSING THE RIGHT PRIMER - A PRIMER ON PRIMERS [URL]http://www.sksboards.com/smf/index.php?topic=56422.0[/URL][/B] How fast a powder burns depends not only on granule size (bigger granules have more relative surface area) but on exterior coatings. Extruded powders, such as relatively small-grained 4895 or large-grained H-4831 depend mostly on granule size to control burning rate. Ball powders don’t vary much in granule size, so depend mostly on relatively flame-resistant exterior coatings to control burning rate. By definition, these coatings make ball powders harder to ignite. For example, in the 30-06, IMR 4895 is very easy to ignite, one reason it’s often suggested for reduced loads down to 2/3 of a case’s capacity.
