    I have an L469 in .222 Magnum. Can I neck size the cases with a .223 NS die?

    Sure, just back the die off enough that it doesn't bump the shoulder. For that matter, you can essentially full length size with a .223 (or .222) FL sizer by simply setting the die for the proper amount of shoulder bump since all three have the same shoulder angle and neck diameter.

    You can also seat bullets for the .222 Magnum with either a .222 or .223 seating die. Just back it off enough that the crimper doesn't touch the mouth of the brass.

    By the way, I like to use the Lee Collet die for neck sizing (quick, no lube, precise neck tension, etc.) Lee doesn't make a Collet die for the .222 Magnum, so I simply use a .223 Collet die and place a 3/8" washer of the proper thickness on top of the shell holder. This keeps the case from entering the die too far and activates the collet at the right depth. Placing the washer over the case slows the operation a bit, but after doing a few cases your muscle memory kicks in and it doesn't really slow you -- not nearly as much as lubing and de-greasing the cases would with a conventional neck sizer.

    Doing just the reverse of this, I cut the right amount off of the bottom of a collet for a .222 so that it was short enough to resize my .221 Fireballs.

    To use a .22 Hornet Collet die on a .22 K-Hornet I simply drilled out the shoulder area inside the collet to allow the wider K-Hornet shoulder to enter. I can still use the same die for regular Hornets, but it now only sizes the upper 2/3rds of the neck -- which actually makes for a better chamber fit and seems to enhance accuracy.

    Lee says they'll make you a custom set of Collet dies for calibers they don't offer, but they said that the 7x33 Sako was too short. But I think they just didn't want to go to the trouble for the nominal $50 they were charging at the time I ordered the custom dies.
