This is the last decapping die you will need to buy. It will do everything from 5.7x28 up to RUM cartridges. It's the strongest and sturdiest decap die I've ever used. The Mighty Armory Magnum 100 decapping die. You can even pick your own color. It has a quick-change pin design, and you can even buy .055" pins for Lapua brass (smaller flash holes) and .357 Sig brass (also uses small flash holes). I bought a whole extra rod w/ a .055" pin on it, for quick-change between .070" (standard) and .055 brass, and it works great.

Spent years using the RCBS universal decapping dies, and kept breaking pins. Then, early this year I discovered Mighty Armory. We also used the MA decap dies where I used to work, so I've talked to Wayne several times at my last job, trying to get a pin design nailed-down for stubborn primers in cheap import brass being ran in AP presses. He's a good dude, with an excellent product, and stands behind his products 100%. Also, his new sizing dies are very nice. We got one of the .223 dies in right before I left.
