I loaded up some 44 mag using brass from a box of PPU 240 gr JHP ammo I shot a few months back. Nice shooting ammo and very accurate. But after resizing and expanding, I can push/seat the bullet with my thumb. The bullets just drop right into the case.

My resizing and expanding die are properly adjusted as I've loaded 1,000+ 44 mag loads without any issues until using PPU brass. I have just about every headstamp you can think of for 44 mag (Rem, Win, Fed, PMC, Starline, S&W, Browning, Midway, Sierra, Norma to name a few). All other brass headstamps have plenty of bullet retention except for PPU. Not the end of the world as it's only 50 cases so I'll just throw them into the scrap pile. If anyone is curious, I did adjust/unscrew the expanding die for less expansion which didn't help at all. These are Hornady dies BTW.

I've reloaded PPU brass for 30-06, 7.62x25, and 9mm without any issues. I'm guessing the case wall thickness on the 44 mag brass is thinner than other brands of brass resulting in a loose fit? I'll measure it when I get home tonight. Just curious if others have had similar problems with 44 mag PPU brass.

Haven't reloaded any PPU .44 brass, but I do get similar results with many R-P nickel-plated and brass .45 ACP cases.

Interesting. I haven't reloaded any nickel cases yet. I only keep brass cases just to make it consistent.
 
Is it because the nickel plated brass isn't as soft/malleable as regular brass? So the cases will crack/split sooner? Not sure.
 
Can you seat a bullet in the sized case without expanding? If not, then case wall thickness / the expander shouldn't be the issue.

I just tried and I can't really insert the bullet into the case. So I just held the bullet in place while running it into the seater die and there is some resistance but then the bullet just drops into the case. I can also push the bullet in further with my finger.

Yup. The nickel plating makes the case more brittle. I tested it several times and nickel always fails WAY before the brass.

Yeah, if it was the expander die, then you'd see it on all headstamps. I suspect the PPU is so thin that the sizing die doesn't squeeze it back far enough. I've had this happen with both Lee and Hornady dies. I bet you wouldn't see this with Redding or especially Dillon dies.

Interesting. So the Redding and Dillon dies are that much better? Well they do cost a little more so you get what you pay for I guess. I'm just scrapping those 50 cases - got plenty of 44 mag brass.
 
I don't know if I'd call them better. Their sizing dies make the brass smaller, which means they probably work the thicker cases more than neccesary.
