    Came across several brass with a smaller flash hole. Can I just drill it out with a drill bit?

    What caliber and brand of brass? Some brass like the 6BR, .308 Palma and the .220 Russian brass used for PPC cartridges have a small flash hole, and it is partly credited for the inherit accuracy of the round.

    I suppose you could drill them out, but I doubt you could be really consistent with the final product. Minor difference could impact accuracy. But if you are not overly worried about accuracy, I don't see why not provided you stay within the larger flash hole spec.

    You can drill it out, however unless it's actually causing you issues I wouldn't bother.

    Looking at the drawing for M80, the dimension should be .078"+.004" so a 5/64" drill would be perfect (.0761")
