[QUOTE="Greyfox, post: 1421207, member: 10291"] I own both the RCBS and Hornady runout devices(shown above). I agree that the Hornady will understate runout when the values are very high, but much less so at typical ranges. Between <.001-.005” of runout, tested with my FL sized Lapua Brass with 140 Berger VLD’s measured off the bearing surface, the RCBS will give readings that are only .001-.0015” higher. With most of my runouts for my rifles running less then .003”, I would consider either device accurate enough for my testing. I find the Hornady easier and faster to use compared to the RCBS which requires some dexterity keeping the case in position while turning it to get a good reading. [/QUOTE]
