No kidding. Greg Tannel is sending my rifle to my as of Thursday 06/27, so I purchased two bags of .300 RUM brass from Sinclair to start with fresh brass. It arrived today. I opened the bag, pulled out a case, and was astonished to see the flash hole was visibly off center. Not just a little, but readily apparent to the naked eye. I took the case while holding it between three fingers of my left hand and spun it slowly with my right. The hole was off center by such a degree that only the edge was in the center, the hole itself described a circle around the edge. I went through the bag of 50 cases and found exactly ten that had centered flash holes. I am trying to think how I can set them up in my RCBS concentricity gage to determine the measurements. I believe a pin gage inserted into the hole would allow me to use a Starrett dial indicator to measure this but I do not have a flat platen to insert into my dial indicator. I will pull out all my gages and accessories to see what I can come up with. I'll need some evidence for emailing Remington customer service to complain, and then send the brass back to Sinclair. I should have purchased the Nosler brass.
