(You need to Login or Register to view media files and links) * 300MP, per Alliant, is a 'little bit' slower than H-110's Burn Rate
* Both powders are stated to be pistol powder but now H-100, introduced in 1962, is sold as a rifle-pistol-shotgun powder
* Both powders are double based powders
* Both powders are extremely fine grained flattened spheres. Some grains the size of dust!
* Both powders are silvery gray in color (the silver has to be the flakes of tin dioxide)
* Both powders possess high grain density, meaning they occupy very little space per unit of measure
Reading up on Hodgdon H-110 in
Propellant Profiles, here are some interesting items that may make 300MP a better powder for use in the
light Schuetzen rifle bullet weight calibers:
** Hodgdon recommends that
magnum primers be used for consistent ignition of H-110
** Hodgdon also recommends to use a
heavy crimp to aid ignition
** My recommendation due to the high grain density, to preclude grains embedded in the primers through the flash hole and aid ignition is ... use an over the flash hole wad. A light paper is my choice so as not to decrease the brisance
Hodgdon does not recommend that H-110 be downloaded and Alliant has no answer or data for downloaded charges. So, plan to determine if this is fact or fiction this weekend for a test using 300MP. Have 20 rounds loaded with the BACO 8.15x46R, 174gr stop ring bullet. Five each rounds: 9g - 10gr -11gr and 12gr. Will chronograph them if Mother Nature allows!
