Does anyone know of any tool, short of a bore scope, to inspect the chamber area of a rifle? I would like to see if there is any buildup in chamber area. I have a couple Savage 10's in 223 and 243. I do load them on the high side and am curious if I am getting any minor blow back. Pretty sure if it was bad I'd see problems on cases. I can tell how clean my barrel is or is not but, not the chamber. And, now I'm wanting to keep an eye on the chamber of all my guns.
So, hopefully someone knows a way that I can afford.

Thanks,
Regis
