lee collet die for 6x45

[cbailey1956]

Hello, As the title states I am wondering if one of the 6mm lee collet dies could be used with minor tinkering, machining, to perform neck sizing for the various lots of 6x45 cases I have. The current lot of win 223 brass has been fired 5 times with the pockets all loose and the neck not holding tension on the bullets. I could play with neck bushings and different expanders but thought a collet die might work. Just not quite sure which 6mm die might work best for the 223 necked up case. Lots of pros and cons said about them and am willing to see if they would work in my circumstances. Thanks, Craig

Annealing will help
Size it with FL 223 die no button then mandrel to set tension.

The current lot of win brass is being tossed but unfortunately i have about 190 primed and prepped cases that have done me good until I noticed this last time that some primers were loose going in and then that bullets were not holding their position after seating. They were annealed last time around. Both my sizing dies Redding and Forster size the neck .004 difference with the redding being tighter. Then the 21st century 243 turning arbor I used ,since it is about .008 smaller than the expanding arbor. Just thought the lee collet system might give me more control over actual size. Thanks for the inputs
