Bought 100 cases from Atlas Development Group in 6.5 CM. Heard about them so decided why not. I have thrown every gauge I own on this brass and every single pc is exactly like every other piece of brass. I used Wilson case gages. Runout tester by Sinclair. John Whidden Go-NG gauges. Shoulder Bump gages. Every single pc was just like every single pc. Loaded up 40 cases and will take them out tomorrow to see if there is anything to fault in the operation side. So far, and with my limited skills, I am impressed. Kudos to the guys at Atlas DG. (Disclaimer...I don't know them, I don't own them I just buy from them).
