Neck Tension for Semi Auto

Then polish the expander ball as previously stated.

Id be wanting to avoid crimping. With that being the case, should I try to bump up tension .001 from my approx. .002 that Im currently getting?

Yep. I've taken .001 off the expander that I use for AR's. Easy to do. Chuck the stem in your drill and hit it with 600 & up sandpaper. Check size often.

It could be overkill, but all drills have a little runout, so I will loosen and rotate the stem 90 degrees every few seconds until it's sized correctly. That way I'm pretty confident I don't introduce (much) eccentricity.

And if using a hand drill, try and stand on a perfectly level surface :^)
