I received my Giraud trimmer today. Thus I have 1200 pieces of 5.56 brass trimmed, deburred and chamfered. The thing works great. It is very well built, it came set up for the 5.56 . I adjusted it slightly for the overall length and went to work. If your on the fence about getting one I would say go for it. The customer service was great. It shipped when they said it would. Their is a couple of weeks wait time. I also ordered a 6.5 Creedmoor bushing and cutter to try. Plenty of videos are available with a Google search.
