So I miked an star machine tool expander plug for 38 special, it was .356 and when used I could feel resistance. I then used a pin gauge set to find what id dimesome 38 special cases were and found .351 fit snug in an resized case.
So I set the plug in the lathe and turned the expander plug to .3495 and polished and blended the bell feature in with the new diaameter. Now my cases on have their necks slightly balled to allow castbollits to be used. I have not done this yet with cast but it seems to works with xtp hollow points.
Does anyone see an issue with this by maintaining a super tight neck tension?
