44 mag seating ?

[cracker]

When seating my bullets I am getting as much as 10 thousands difference in col. I am using a lee press and hornady dies. These rounds are my plinker rounds of 7 grains of titegroup and 240-grain hornady swc. Brass is all trimmed the same size. These are 44 mag rounds and I know that the difference will not matter much in my shooting but it bothers me as to why the difference. Any and all ideas are very much appreciated.

Have you measured/compared bullets? As long as you are crimping at the same spot in the cannelure, I would not worry about it.
