I have just started reloading .223 cartridges using Hodgen Varget powder. Using a .223 inside neck diameter setting on my Hornady collet type neck die, I was not able to hold the bullet seating using 25.5 grains of Varget (a partially compressed load). The bullets are randomly backing out after seating, given as much as .012" variation in overall length (using a Davidson length measuring tool).The Nosler BT bullets I am using are .224 in diameter, for a .001 interference fit. I decreased the inside neck diameter to .222" and now the bullets are remaining seated, within only a .001" variation in overall length. Has this been your experience when loading Varget in the .223?
