    The difference between a 270 and proper 7mm, 9 thou is roughly 0.2mm.

    270 is a harmonic divisor number[1]
    270 is the fourth number that is divisible by its average integer divisor[2]
    270 is a practical number, by the second definition
    The sum of the coprime counts for the first 29 integers is 270
    270 is a sparsely totient number, the largest integer with 72 as its totient
    Given 6 elements, there are 270 square permutations[3]
    10! has 270 divisors
    270 is the smallest positive integer that has divisors ending by digits 1, 2, …, 9.

    That's because 7mm it is the calibre of the bore, the whole before the grooves are cut. The bullet has to be wider than the bore in order to create a seal in front of the building gas pressure.

    0.009" * 25.4 = 0.2286mm

    The .270" BORE is also commonly known as 6.8mm. The difference in bore size is roughly 0.2mm between that and a 7mm BORE.

    There is nothing wrong with my maths and I have the cirtiphicats bits of paper to prove it.
