Neck Sizing with a Bushing Die without Neck-Turning Cases

[gunsandgunsmithing]

For the mandrel users...there is no right or wrong answer here and I don't wish to argue or take this far off subject.

But my question is, for short range primarily, do you see a difference in group size on target as opposed to just using a bushing and no mandrel.

I realize well that if we believe something helps, then it does but I'm curious what others see on the target in terms of consistently better or worse accuracy, both ways...with or without neck turning and using a mandrel in the process. I can't say that I remember testing this but it has become popular. I'm more interested in the targets than the logic.

I understand it but I'm curious if someone might share what they've found that quantifies any difference, both good or bad. TIA!

Your previous post was very good at quantifying the differences you see in the brass but I'd didn't see how it fairs on target. Admittedly, I may have overlooked it as my eyes are heavy already this evening.

I was shooting a sizeable jump and could see the diff on target with those bullets marked with the black sharpie! I know there is a degree of concentricity threshhold that dosent make a hoot but my point is if you work your neck too much to get to that point then your tension is compromised..and that, we know, is a factor! The less you mess your neck the better. So best to do it one time up front with new brass, if required.
