Is normal some marks in barrel's feed ramp 9mm,(400 rounds) the mark are  more deep in the edges feed ramp, the form of marks is like a arcs that cross edge to edge.

Thanks.

Can you post a picture? It's hard to say without actually looking at it.

I have not camera, but the feed ramp  look  rough  with this "lines" that cross edge to edge and are  more deep to the edge.

Thanks

Are you using factory magazines?

Both of my P99's feed ramps are smooth and polished looking.

I had one P99 that had a few machine lines on the feed ramp, but they didn't effect feeding.

I have some on mine, but they have been polished to feel quite smooth. It works just fine.

Thanks for information, in the pic of Bibon I made in circle the  site of  mark,  I have not problem, but is posible that some type of ammunition cause this mark?

Those look like machine marks to me. Done at the factory. I'm 99.9% sure that ammo won't cause that.
