I thought it was just me...
I've been trying to decap some old 5.56 brass I had in storage for the last few years. I successfully decapped two casings and then the decapper pin on my Lee .223 die broke. I thought I hadn't lubed the casing properly at first; when I pulled up, the rim sheared off. I had to hammer the casing out with a steel rod, the decapper pin was stuck in the casing. I had to wrestle with a leatherman and a vise grip to get the casing off the decapper pin, which was snapped.
I had tumbled 4 batches of brass the day before, about 3 hours for each batch to make them cleaner. Then I soaked them in an old fashioned mix of vinegar and brine to get the patina off and tumbled them again after they were rinsed and dried, making them almost factory fresh and clean.
I discovered that a large part of my brass was South African surplus with Berdan primers after I broke my Lee Decapper Pin from my .223 Lee Loader kit.
Grumble..I went online and ordered replacements along with some other tools from Midway. It was my own fault, not Lee's.
But now I'm running into other problems. I culled my brass of South African surplus. It's mostly Lake City with a few Winchester White Box, and some PMC. Before I pulled the pin out of another die set to ruin, I bought a Lee kit at a local feed store yesterday. The packaging boasts,"Decaps even the most stubborn crimped primers!" I bent that one on a Lake City casing and it snapped when I tried to straighten it on the first casing I tried. I took it back this afternoon and swapped it for the last kit they had on the hook. I just broke that one after decapping three more casings, it warped on the first casing. Two were Lake City and one was PMC. It broke on a Lake City and the primer is halfway out, even after I tried popping it out with a masonry nail and bent two 2D finishing nails. It's like the primers are welded to the flash hole, all the Lake City flashholes were deformed after I got the primer out.
At this point, I think I'm going to cull out the non-Lake City and sell the rest for scrap and buy brand new, unprimed brass.
How can brass beat steel?
