RE: diffrent bullet brands and OAL???????
sounds to me like somenoe should have read a book about reloading before they got started.Might i make a suggestion?Go buy a reloading book like the one made by lee and read it cover to cover and tell us what answer you found.
you should always know as much as possible about something before attempting to go whole hog and get yourself killed.That is going bear hunting with 22 pistol and a jar of peanut butter!DUH!!!
