    It is basically 50 AE necked does to 44mag. Anyone loading this caliber? I’m getting ready to order a barrel, and already have the dies for it.

    The cartridge has been around for a couple years now. But so far, actual loading data seems to be pretty scarce. I’d be half interested in getting a barrel if I came across a good deal, but it’s never been a priority.

    I have found I can make the .429’s advertised 240 gr. @ 1600 fps velocity from the .44 Mag barrel with a couple published loads anyway, so I’m not sure what the .429 would gain me. ETA: this was from a 10” barrel. But I have gotten slightly over 1500 fps from a 6” barrel.

    Then again, it would be interesting to see if someone could (safely) hot rod this thing. The older .440 Corbon reportedly pushed a 240 gr. bullet to 1800 fps from a 6” barrel.

    As for actual data, the closest I could find was someone doing some Quickload workups over at https://www.sporterizing.com/index.php?/topic/12613-429-desert-eagle/. The 2nd page of the thread has some chrono data topping out at 1500 fps. So again, still in .44 Mag territory.

    I may still get a barrel eventually. But I would like to see some actual load development first. I have a funny feeling this one won’t be around all that long. I would consider it still halfway in wildcat territory.

    The 440 Corbon data was where I was going to start.

    Thanks for the link! I’m not planning on pushing it to the max, 1500 fps would be fine for me. I don’t want to beat the gun up.

    I want this just for the fact it is odd and unique. I expect they will drop the 429 like they did the 41 mag and 440 Corbon.
