Can someone please measure the ID of your 380 cases after being sized?
Mine are running around .354 as best as I can measure.
Lee die says 380 auto, so it is marked right.
Sized in my lee 380 die, lee 9mm die and RCBS .223 die (I was trying everything last night).
Severe lack of case tension in all, with .355 jacketed.
Even without using the expander at all, just size and then seat.
9mm cases sized in the lee 9mm die were around .352 and had plenty of tension.
9mm cases seemed to be a thousandth or two thicker than my .380, letting the die size id down more.
I managed to get enough case tension when using my last batch of commercial cast hitek coated .356 bullets.
I just brought home 1K Freedom munitions .355 plated 100gr from the NRA show and am having case neck tension issues again, seat the bullets and you can push them in by hand.
I am going to order the dillion die set later (I prefer seat/crimp in separate steps anyway), just wondering what others are getting for sizing.
Also trying to gather data before contacting lee.
I would like to sell the die set off to offset some of the cost of the dillon set, but cannot sell it if it wont work.
Thanks,
Matt
