Well made
Just one warning. Watch out for the set screw when you open the package. It was just loose in the bag and off it went! Never did find it so off to the hardware store. Otherwise very nice item
Underrated
Works great!
Underrated
Quick,easy to use, have it in 6mm & 6.5mm. Woulden't trade it.
NECESSARY FOR WALL THICKNESS GAUGE
Works as intended
Nice but worthless
As the description reads, they're for checking neck runout on new case necks. But who checks even new brass neck runout without expanding to ensure any factory deviations are pushed out and the inside of neck is consistent. Even Sinclair's reloading procedure recommends it. However, Sinclair's smallest expander measures .2815" and #26284 pilot stop measures .2735, an .008" difference leaving a lot of slop. Review also applies to the 223 pilot and the review there by another is pretty much valid!
Too Small, Bad Fit
The pilot is well machined to the wrong dimensions. The one I received measures 0.3460". Even when I use an undersized sizing die on my 357 magnum brass, it's a loose sloppy fit. I tried the 9.3mm stop, and found it measured 0.3555" to 0.3560". That will fit very tightly in some, but not all, of my .357 brass. And I can use lapping compound to take the diameter down slightly. However, there's nothing I can do for the "35 caliber" part, since it's already so undersized.
Way Undersize pilot
The 22 cal pilot I received measured .212. Tech support said they were designed to be .007 undersized. If you assume the 22 cal intended was .224, then .007 undersize should have been .217 and not the measured ,212. This leaves so much slop when the neck is placed over the pilot that when rotating the case for a measurement, results are erratic.The same pilot issue occured with the 30 cal pilot. I sent the whole thing back tool and pilots and purchased a Redding. The Redding pilots are .004 below caliber which is perfect. Sinclair would have a very competitive product if their pilots were sized correctly.
