    Nice. So the top case has been fire-formed and the middle has been hydraulically formed? So load it up and square it off then.

    Expensive landed? Did you send them 5x fired cases or do they have 260AI in stock?

    Very nice!

    So what's the tucky with this AI carry on? If I'm getting 2800fps with a 143 eldx in stocker 260 am I going to see much more if I went to AI?

    Maybe 150-200 fps more depending on barrel and action. Not (real world) worth it Imo.
    I was bored and wanted a project so had one done ages ago.
    It turned out primo but there was a lot of learning to be had.

    Glad I done it but I won't be rebarreling to the AI if I ever shoot it out. Would just go with a standard .260 or another caliber.


    Then again if I buy one of these dies😆

    I just want to explore something different in a short action...and when I came across this forming process I was hooked as it is another gadget. Got to get into some serious load devt now. My 142gn LRABs were 3007fps with R17, but it was killing primer pockets too quickly.

    I was referring to the top case in the photo, it looked to have been fire formed as it was blackened on the neck. @Tikka7mm08 is this correct?

    So it just gets you closer to the finished capacity then so there's not so much variation between forming loads and already formed loads?
