I'm not quite sure if its true or not but I read a couple years ago that standard 209 primers are too hot which causes the bullet to make a minor jump a little in the bore before the main charge ignites.
The primers for MLs aren't supposed to be as hot, eliminating this jump.
Cecil Epps use to say this very thing a few years back maybe even now. I have never found it to be true unless the powder under the load is damp or fails to ignite right away... guess it goes back to the old thing keep yer powder dry!
