Has anyone found that the black coating on the barrels is causing the rounds to feed hard into the chamber? Will a chamber bore clear all of this out? The reason I ask is my rounds are rather difficult to chamber. I have to use the forward assist with almost every round. When they eject, there is some black residue on the casing that doesn't look like burnt powder. I've chambered a round and pulled it out and there are no chamber marks on the copper so I don't think that is any issue. This is only happens with Independence 55gr FMJs. I can shoot PMC X-Tac without any issues.
Thanks, Adam

You have a minimum chamber and the ammo is probably on the max side. If you can shoot one brand and not the other that is pretty diagnostic.

Thanks for the info, Greg. Would it be possible to have the chamber machined so that I may shoot all types of ammo?

You could drop a reamer in there and clean it up but my choice would be to stick with mainline ammo if I didn't reload. It may well be only that lot from them is "tall" . I would measure the shoulder movement with various ammo and see what the variation is from the unfired to fired.
