I am starting to take an interest in loading my own .270 rounds and in a fit of boredom thought it might be interesting to look at the difference in two factory loads I use, RWS and Norma both 150gr.
thing that struck me is the bullets are different diameters at .277 (norma) and .278(RWS) (actually between .2781 and .2784 if I am going to get pedantic)
It doesn't seem much but it is visually noticeable and surprised me!
is this unusual?
all seems to come out the hole at the other end quick enough.
