Hi. I have the former. It's not as thin as you make out, and the actual thickness varies. It flares out somewhat towards the back end, starting at the receiver pretty much.

I haven't opened up max in nearly 2 months so I decided to start with something simple. 5.7x28mm and 12.7x99mm
Model are 90% accurate. I could not find measurements for some areas (ratio between rounds might be a bit off as well). visually, how could I make it more accurate? (ie. shader, material, etc.)
It looks a bit rusty..
the bullets I have around are kinda old and I was basing the material off it. lol. I have a few used shells and old bullets laying around.
Find something brass and something copper if you're having trouble basing it directly on the rounds. Work from those.
Still sharp. They should be smooth enough to catch a good amount of edge high lights.
Don't round things off more than you think they're supposed to be, but remember it is much much easier to tighten support edges that are too loose than it is to loosen edges that are too tight. So, err on the side that takes less work to correct..
This is what my first reaction was.

Make sure it looks similar to that, though not exactly the best looking image, the bullet has a brass appearance, with not THAT many scratches and divots as yours.
