[QUOTE="budlight, post: 2802561, member: 2939"] That is only true of some auto loaders. I have zero dings in my 3 AR-10's cases. you would never know that my 308 brass came out of a semi. Years ago I had a AR-15 that scratched the necks on the 223's. It was a stainless 18 inch with a SS BCG. The only thing that I could see doing it when slowly manually ejecting the empty polished cases is that the ejector was swinging the case causing it to drag across the very sharp barrel bolt lugs. I removed the barrel and rounded/polished the chamber sides of the locking lugs and the problem was gone. I've also see dented cases caused by short gas tube length guns. I only use rifle length and r+2 inch. Higher pressures of carbine and mid length are much more violent because of the increased pressure at the gas port. The key to pressure drop is longer and smaller diameter gas port holes. I only use the heavy full auto bolts, light flat wound springs, and the lighter buffer tube weights. [/QUOTE]
