Thread: Hot vs Cold Primers, Load Data

as i said...thats the bottom end of things....so maybe...it does make difference if trying to go subsonic..a magnum primer was worth close to 2 grns of trail boss EG load would crack unless dropped 2 more grains of powder....
ap70 LOAD IS BULKY so shouldnt need a filler UNIQUE is in same boat....in a big case,maybe an issue,maybe not.std primers worked well for me with the lighter loads,but magnum still went bang....
why not ask the question you are dancing around and be done with it??????
will primer X be ok in XYZ load in QRST case????
