Glad that you weren't injured seriously.
In nearly 50 years, I don't think I've ever seen a case failure just like that in your photos. Just ahead of the extraction groove, yes, a very few. In that groove, no. Very strange and a bit disturbing.
As I was unfamiliar with the brand, I did a Google and went to their website. From what I could gather there, it would appear that most, if not all, of their ammunition is "remanufactured". This assumption would seem to be bourne out by the "FC" shown on the case in your photo's headstamp. IMHO, this could be a potential issue for you, warranty-wise, when you contact Kahr. Virtually every brand of handgun I've ever purchased had a specific clause which declares the warranty will be voided if "handloaded or remanufactured ammunition" is used. Don't know if this is the case with Kahr products, but you might want to check your manual.
One possible cause for the case failure might be that the bullet was somehow "set back" into the case upon feeding, which could very well cause a major-league pressure spike and cause the case to rupture. I have seen this sort of thing before, but usually the failure occurs just forward of the extractor groove where the case is partially unsupported at the feed ramp in some pistols. The logical culprit in most of these instances would seem to be poor bullet fit with the particular case and/or a weak "crimp".
Hopefully, Kahr will go ahead and fix it for you under warranty. If they don't, your only recourse may be to contact Ultramax and seek redress from them. Good luck either way.
Glad your ok. How many rounds of lead bullets have you shot through the polygonal rifling of the Kahr in the past? Most likely a over charged round though.
YES, me too, I am going to stay away from ultramax till I hear the "rest of the story" .....Glad you're ok.
I have seen lead bullets leave enough residue to not let the cartridge fully seat and expose enough of the case to blow out the back of the brass.
I wouldn't shoot anymore of the unjacketed bullets in any auto.
I'd like to hear the final verdict on cause and damages.
Glad you're ok.

Glad to hear you are basically okay. Isn't Ultramax reloaded ammo? Some info from the Kahr FAQ:
I've never heard of the grip panel popping open before, but it seems to fit your case.
Looks like ultramax just bought you a new gun. Good to see you're safe.
I saw a special on rounds that were improperly seated or pushed to deeply into the casing that would tear up a gun like this. I do not re-load but it said to little air space for expansion??? I am no expert but it was about explosions similar to this one.
Lead bullets, poly rifling equals no no
