I’ve started playing with 458 SOCOM. I have the Lee 3 die set with sizer, expander, and bullet seater/crimper. The instructions say to put in a round that you’re duplicating in order to set up the seater die. But, I’m not duplicating the rounds I have – instead I’m using hardcast 300 gn. So I just guessed on the seating plug and figured I could “walk it in” if I was too long.
As you can see, it’s not even seated to the cannelure yet. But, it’s shorter than the closest thing I could find in my reloading book (Lyman 50th ed). That was a 300 grain flat nosed round and the OAL should be 2.145” The one above is currently 2.067”.
So, I guess my question is, do I keep seating it till I get to the cannelure and disregard the OAL? Or do I need a longer bullet?
