Update on my shells. Measured the chambers and the brass. Smoked a few and they are all big at the mouth of the case. The chamber measures slightly tapered. The brass is about .006 bigger. Machined a mandrel to hold them and indicated it in and using a brand new 12 inch file I carefully removed the excess material measuring as I go until they chambered. Also had to thin the rim .010 and round them some. Just a deburr really. Takes time but at 10.00 a case you don't want to scrap any. Made a drawing with dimensions for uniformity. Going to take a little time to do them all and it is so hot here in Ga. I can only work in my shop early in the morning or in the middle of the night. Do these cases take components for a 10ga or do I need to use 9 ga wads? The case wall measure .030 thick minus the .006 I machined so they are now .024 thick. Inside dia. is the same. Thanks everyone for all the help.
