    Im working on a 3d printed mag for the fx impact. I need to know from those who have the Impact's what size the outer diameter of your probe is.

    I currently have the .22 cal and .25 cal probes on hand.

    so i need the .177 & .30 cal. I could possibly do one for the .35 cal but i think I would need to redesign the outer casing to clear that big of a barrel. 

    Any help would be appreciated.

     

    a pic of what i got going on.

    Though I don't have a 35 caliber Impact barrel, it stands to reason that the probe is at least .357" in diameter.  It is more likely closer to .360" or more because the brass breech on my .30 caliber is proportionately that much bigger and sealed by an o-ring.  I'd print the .357 loading tray with a .362" hole for smooth operation.

    Wow. I’d have figured  with all the other probes  being oversized the .177 cal would be as well. Thanks for the measurement.
