I was sizing some more 357Sig brass using the LEE die set, anyway I was sizing a Speer nickel case and the priming pin became stuck/broken in the flash hole of the casing. The LEE pin is dsigned to pop up, but that didn't happen. The pin stuck and broken was very tight inside the flash hole and I had to drive it out to remove it. WORD OF CAUTION! It seems that these flash holes are smaller in diameter on the speer than other brands of 357Sig brass!<!-- Signature --> Well I sent LEE an e-mail via their website and here is their response... Well it is another A+ for customer service from LEE This makes me wonder if Speer is using smaller flash holes to better contain pressures with certain loadings. Oh well, I'll be drilling out the flash hole so it doesn't happen again! This may have to do with the nickel plating process, which is building up inside and closing up the holes on some of them! Well I can rule out the nickel plating as the cause, all of the Speer 357Sig brass had the small flash holes, How do I know this? I just finished drilling every last one of them out and depriming by hand. A 3/64" drill bit worked way better than 1/16" for opening up the holes, Now the holes are the same size as all the rest of the other 357Sig Brass... Wanna kill these ads? We can help!
