Works very well

Purchased this along with the press adapter and an expander mandrel. Tried to use them in my Co-Ax press but case mouths were getting crushed. Too much play I think. K&M doesn’t recommend this setup with the Co-Ax so that’s on me. Installed in my Rockchucker and it’s very smooth. I really like the ease of setting case mouth tension with these tools.
Neck Expander Tools

The neck expander press adapter, expander window riser and expanding mandrels all work very well. The window riser allows fast adjustment of the expander to prevent case neck crushing. It allows the use of the expander without the stop screw; this makes case feeding easier. K&M makes great stuff!
