Two things to check for loose bulletheads with no crimp.
1.Make sure you have good brass. Some times the thickness of the brass (rarely but worth checking) is to thin. But make sure its rebutable like federal or remington or winchester.
2. On your seating die setting follow this.
a.) with no crimp seat one bullet to your desired depth.
b.) leave the bullet on the press (in the shell holder)remove your seating plug from the die, loosen the die collar.raise the bullet into the die and start turning down the die till you feel resistance.
c.) Lower the bullet and turn the die in 1/2 a turn. That will give you a slight crimp. You want just enough to hold the bullet in place. No more than that. If that isn't enough turn it in a little more.
too much crimp will give you internal pressure problems, and dramatically effect your accuracy.
d. lastly raise the bullet into seating die and screw in you seating plug so it just touches the bullet and lock it down.
