Bimmer, didn't realize they were that pricey, but I haven't had to buy any outright recently.
Dillon had sent me the new 'failsafe' powder measure, and I contacted them that my old charge bars were binding in the new measure.
I had acquired a number of charge bars over 30 years, and, God bless 'em, Dillon replaced them all. Their customer service is first rate.
But I concur, even if you have to flat out buy them; huge time saver, and it prevents mistakes as well.
