Whereas I have no objection to appearing pedantic - hell, I am
a professional pedant :-)

It is m(v^2)/2. So, the ratio is (m1(v^2)/2)/(m2(v^2)/2). Cancelling
common factors, one gets m1/m2. You also may have missed the fact
that a .177 pellet has 1/14th the mass of a .22 bullet - both the
type and calibre are different.
