Bullet seating issue - RCBS 338 win mag dies

[rajb123]

I reloading about 100 reounds of 338 winmag ammo last weekend and it went without a hitch.

Last night, however, had an issue with the bullet seating die. When I attempted to adjust the die to seat the bullet deeper to the correct length, the bullets kept getting pulled back out of the brass and getting stuck in the die.

I'm stumped.

Did I adjust the die in the press incorrectly? These are belted cases.

thx...

Correct adjustment would be by turning the seating stem down more. If you turned the die down, the case mouth will get crimped. The seating stem nose should be a good fit to the bullets ogive.
