I reload 40 different ctgs, so I have a LOT of dies from almost every mfg. I really like Lee dies, especially the Collet style for rifle calibers. They work perfect for all my AI ctgs.
HOWEVER, I just don't understand why Lee persists on using those 'mickey mouse' lock rings with the 'o' ring lock. I just don't trust the ability to 'lock' when I screw them into the Rock Chucker.
I just purchased a lot of 11 normal split ring type lock rings on ePay for cheap.
I have been drilling and tapping the Lee rings for a set screw.
Who wouldn't pay a $1 (or so) more for a Lee die with a 'real' lock ring?

Sorry, I just had to unload. ha ha
