Case neck and overall dimensions checked throughout processing with a Sheridan Engineering Gauge to ensure that the cases function in even the tightest SAAMI chambers, and we use digital calipers to ensure a consistent length of 1.358 +/- .010 We also batch check cases with a Swage Gauge to make sure they are not over or under swaged. Cases are ligthyu swaged, if you run on a progressive you may choose to ream or chamfer the pockets.
