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.
