Hey guys, I heard about an old .429 wildcat, the 44 Alpen. Supposedly it's based on either a 300 win mag or a h&h mag case with a .429 bullet on top, but i cant find any other info on it no matter how hard I search. So, do any of you know about 44 Alpen? What case is it actually based on, maybe case dimensions, or if one has ever been seen in the wild? Maybe even a picture?
