I picked up a set of Lee dies for the .50 AE for a buddy. I was going to load some Desert Eagle ammo for him. These are not carbide as Lee does not offer them in carbide. I used my normal Frankfort Arsenal (MidwayUSA) spray on lube (formerly known as Minute Lube). The brass cases were no problem. I tried some of the nickle plated cases and things got bad. I stuck the first case and ripped the rim off. My trusty RCBS stuck case remover got it out. I switched to my standby lube, Rig Lube +P. This stuff works on the tougest rifle cases so it should be fine, right? Wrong. Stuck the second case. Then I broke the tap off in the case. Now the brand new sizer die has to go back to Lee. I ordered some Imperial sizing wax. When the die comes back, we will see if it is really is as good as they say it is.
