.45GAP: Ramshot True Blue
Disclaimer: The powder charge information (in black) was taken from gun powder companies, gun powder distributors, and/or published handloading data (paper and/or electronic) to the best of my knowledge – not responsible for typos; Always refer to published official handloading data for verification.
Pressures may differ significantly due to component variations and whether a test barrel or an actual pistol was used for testing purposes. I am not responsible for your actions. Powder charges that are too light or too heavy can both cause pressure problems. Use your own common sense. If you wish to use any of the following data, use at your own risk! You are responsible for your own actions.
WARNING: Red lettered data in charts refers to loads that have not been officially pressure checked and may be beyond maximum pressure limits --- extreme caution required.
(I threw no data out as fliers; no special measuring – just cranked out the rounds on a Dillon 550 press)/ True Blue is the most efficient Major Power 45GAP powder I've used, expecially with the heavier 200 and 230 grain bullets.
