[QUOTE="Bob Wright, post: 2330947, member: 104363"] For 2 of my rifles, both smith's used tight neck reamers. I found out the hard way on the first rifle when I knew a whole lot less than I do know, in reloading. Once I had evidence of over-pressure on the first rifle, another Smith locally asked the right questions. Does a bullet easily fall into a spent case? Nope! It took a little bit of alignment to get that bullet started but there was resistance, ever so slight. After casting the chamber at home, I know the exact diameter of the chamber neck area. Both rifles now get turned brass to establish. 004-.005 neck clearance on the diameter. Alternatively, one can mic the loaded necks and spent case, and get close to the actual clearance, depending on work hardened brass/springback. I still mic the wall thicknesses on a sample basis to monitor because I am curious and have found inconsistencies later on. Factory offerings probably never need neck turned brass due to small chambers, but it still should get the "bullet slide in test" just to be sure. I still prefer to just turn those necks to knock off high spots, for 50-75% cleanup. I'm moving to a mandrel die soon. Even though I use a bushing die, I think the mandrel will do as was noted above.
