So I have good like with both powders in my 30-06 rifles at reduced loads found in layman's data and hodgdons directions on line. That said my question is.
Which of these powders generate more gas volume and will the increase in gas volume increase my port pressure on a M1 garand.
I ask only because I'm working up loads for the M1 garand and would like the rifle to cycle on the lowest charge that I can get decent accuracy with.
