Is there a FL die that sizes down 6.5PRC to eliminate clickers?

[QUOTE="VinceMule, post: 3065193, member: 122164"] Clickers are an issue of a mis match between Full length die dimension and the Chamber dimension. Alex is an expert on this issue. Use of micrometer that reads into the .0001 is mandatory in determing the proper size die to use. Measure: Dia at the .200 one on New brass Once fired brass three times fired brass .0005 is a country mile Now measure the dia that the die sizes the brass down to. Your problem will be revealed in the numbers. As brass gets fired 10+firings on hot loads, the Brass springs back even more where the micrometer tells all. Many times, our most accurate load will be at top end pressure, no way to get around it. Why build a hot rod to have to back off on the load? Lapping the chamber out .0015 with 320 grit wet sand with oil takes 30 minutes with the barrel in the lathe. This may seem helter skelter, but chasing expensive dies to size down to an undersize chamber or over size new brass is Just as crazy. It is madness to invest $300 in a die for the fix, just to find out the die is not what it is supposed to be, screwed up in heat treat. It would be great if we could have a set of "web sizers" graduated in .0005. [B] Then again, just have a gunsmith do the job in the first place that has put in the time and money so that his phone will not ring from dissatisfied customers.[/B] There are some issues with PRC's with die vs reamer, Alex Wheeler has invested the time and money to solve these issues, and I would not rush to ask a guy to give up his trade secrets that allows him to make a living. There is a relationship between new brass dimension and chamber dimension, and for hunting rifles, .002 is way too tight. If you go large, you may lose primer pockets prematurely, so there is a balance. Variations in web dimensions in various brands of brass is one heck of a mess. Soft brass can leade to Clickers, some brands more prone than others. The .0001 micrometer is your best friend in this issue. [/QUOTE]
