Ok heres the situation. Im trying to figure out the bullet seating depth. Im using 150gr. Accubond bullets and nosler says the max. total length should be 2.860 but when i do what nosler says with flattening part of a used case then putting a bullet with perminate marker on the whole bullet. and finding the length when cycling the bullet it is about 2.961 and can't even eject. Im using a browning a-bolt 300WSM white gold medallion. if anyone can give any advice would be great.
