What seems to be missing from this whole equation and it is
mentioned in most reloading manuals is the following; one it's not
the same gun your mileage may vary: it is not the same lot of powder,brass,primers or even the same dies so I would expect some differences overall. Also what was the tempature while
shooting in each case. same lot for bullets? You are correct it is only a guide and every rifle is a law unto itself ,happy
hunting. PS not an expert and not flaming anyone,just
my very small .02centovos Cheers NC


don't judge until you have walked a mile in other persons' moccasins'
