2. I can't seem to get it adjusted to reliably trim each case to the same length.
I took my Wilson .308 Win, .243,260,7mm-08 ect. shell holder back to the place of purchase, out of the five other shell holders in stock I found only one that was bored correctly. The result a Wilson shell holder bored off axis is that the case is not trimmed square, and depending on where you measure it you will get different reads.I had a problem with the Wilson trimmer, the hole bored in the shell holder was not concentric with it's out side diameter.
