    Do any of you guys know which brand de-capping (de-priming) die works for the long cases such as the 7mm Ultra Mag? I've searched the web and can't find much info on this. Some die manufacturers list 2.5" as max and others don't say. I saw one review that stated the guy had used a Lee for his .300 Ultra Mag.
    Thanks

    I tried my RCBS Universal decapping die on a 338RUM case (2.76") and it wouldn't work, but I don't know which one will. Sorry

    While waiting for a response, I kept nosing around and finally found the Sinclair. It's twice as expensive but considering if I had to go with another brand and buy two, what's the difference.

    Thanks guys.

    I use an RCBS Universal Decapping die for all of my loading and it works just fine with the 7mm AM, based on the 338 Lapua cases as well as the 270 AM and has plenty of adjustment left for more length. The die body does nothing but serve as a holding mechanism for the decapping rod/pin and nothing touches but the decapping pin.

    I didn't go with the RCBS because the spec sheet stated a maximum 2.50" case length.

    My Lee decaps everything, including RUM's.

    I looked at the Lee but everyone was backordered.

    Thanks for the response!
