Hello. I managed to get some federal gold medal match 150s for use in my large pistols. I had always used the regular 150s (not the match) for my 45 colt loads with very good results. i have added 45 acp to my reloading dies and i am woking up a load at home (my range is not accessible to me at the present time due to covid). I just read one of the older treads on this forum that once I use federal primers in my brass, that I could no longer use any other primers as the primer pockets would be too large for the other primer brands. Is this correct? An old wives tale? Has anybody had this experience? Thank you for any help you could give me in this endeavor.
