[QUOTE="VinceMule, post: 3014303, member: 122164"] We have "fought" clickers for 30+ years. The first lesson to learn, never use calipers to measure the web, use a good micrometer that measures to the 0.0001, and it does not take a very expensive micrometer. A machinist would tell you to never use a caliper to measure in these small increments for reliable results. I have Helios, Starrett, Brown and Sharp, and Mitutoyo dial calipers, but when measuring diameters in the web, I always reach for a micrometer because .0005 is the difference between a clicker and no clicker. This inexpensive brand is an excellent micrometer for the reloader, and it will last you a lifetime: [URL unfurl="true"]https://www.ebay.com/itm/331107299140?[/URL] Clickers are a function of Reamer design, New brass design, and Full length die dimension, and machining techniques that will cut to true reamer dimension. Reamers wear over time. Sage advise an old German Gunsmith taught me: A. Measure your new brass at the web B. measure fire formed brass at the web or .200 line C. Measure brass at the web or .200 line where the bolt handle starts to feel the [B][COLOR=rgb(184, 49, 47)]slightest[/COLOR][/B] amount of resistance D. Measure the Brass at the web at the .200 line where a Clicker occurs or where increased bolt lift is noticeable E. Measure the dimension of the brass at the web where the FULL length sizer reduces the web [B][COLOR=rgb(184, 49, 47)]Record all dimensions to the .0001[/COLOR] [COLOR=rgb(0, 0, 0)]Learning to work off the numbers vs working off of feel gives you a very clear understanding.

European brass used in SAAMI spec chambers can be a nightmare. A basic question to ask yourself, "how much over new brass dimension should my chamber be?" For Example: new 223 brass in a couple of brands, web dimensions: Winchester- .3700 Hornady - .3715-.3720 Nosler - .3722[/COLOR] [/QUOTE]
