Recently ordered two 6.5 Grendle uppers. In the picture from left to right: one unfired round, two cases from upper number one, two cases from upper number two. Hornady Black 123 gr ELD MATCH #81528 factory ammunition.
Supplier of uppers to remain nameless until I've worked thru this and some other issues with them.
Upper number one doesn't extract brass. Have to pull down on charging handle and mortar weapon to extract brass.
Upper number two extracts but has similar marks on case and bending of rim from extractor.
Both uppers were cleaned well prior to test firing. I don't have a chamber brush but I did clean chambers with old chamber mop covered with a Rem Oil soaked patch. Seemed to fit just snug enough to clean well. Chamber and bore were cleaned until patches came out white. Cotton swabs, pipe cleaners, ..... Usual process for me with any new firearm.
Chamber mop used is one from Hoppes, "Cotton Swab". Also used the Rem Oil to spray (hose) out chamber.
Is there something further I can do here? Is this just a dirty chamber and I need a chamber brush of some kind? Or is this something that needs to go back to manufacturer.
Thanks
