Newbie question

[ning1986]

Hello all,

 

This may be a newbie question, since this is the first shotgun I own. But when I'm cleaning my Benelli m4, I looked inside the bore, and there are bunch of scratches towards the chamber, is that normal? it smooths out towards the muzzle. When I first got this gun, it was smooth all the way.

 

I've attached a cellphone picture for reference.

Hard to tell from the pic but that looks more like plastic residue from wads. Chamber area gets hot and some of the plastic rubs off in the forcing cone area as the wad/shot head down the barrel.

I'll try to take a better picture later today using a better camera, but this picture was taken after I cleaned the gun. I would suspect that plastic reside couldn't stick to the sides since the next shot would no doubt melt it?

Negative. Google "plastic wad residue". Welcome to shotgunning.
