9mm Brass wont fit into my Resizing Die??????????????????????

[ballbags]

I picked up 1200+ - Allegedly "once fired" While sorting it and inspecting/culling out brass I ended up with about 600 or so unfired pieces .
upon resizing some I kept running into "MAL 85 9mm" that would not go into the Die and I will not force it. Any thoughts Please Chime in as I am at a loss here
Pretty sure the MAL is Malaysian surplus as I have plenty of 5.56 on hand

I don't quite follow. Carbide die or lube? Won't even start or just swelled at the base? Need a bit more detail.

My Bad (LOL)
It is Dillon Carbide Dies , and it will not Start and I am not going to force it, all other brass Win Rem PPU Horn all go in without issue
Will take Dimensions of it and Post Pics

OK but if they're carbide dies they should be fine. I'm using my Dillon right now with .45 and you get hard size and easy. No difference. I still think it's just a bit of base swell and you shouldn't worry. Which Dillon is it? Mine's a 550 RL. No bells and whistles. Older one.
