Shawn Carlock, i just had my edge returned to me. i loaded 300 grain bergers at4.020 an they wont feed so i cut back to 3.970 still wont feed... now i stuck a dummy bullet in a case that split so the bullet would slide easy with in the case and got over all lenght of 4.030..... i'm pretty sure the bullet was off the lands.. So i went back to the 250 smk and they feed fine at 3.795 but the bergers are much more tappered than the smk's what do you think my problem is???? do i have to resort to 3.785 oal?? its suppose to have a long throught though..
