I was curious about this a year or so back... But read replies on this forum and steered away from it.

The idea of mashing rounds back into concentricity wasn't popular.

tried it...returned it to friend who wasted HIS money. so much measured runout is is the case, not bullet in the neck. you can't correct the case problem except frequently by firing it several times(sometimes only once). bullet runout due to neck problems can be worked on by outside and/or inside neck turning. small runout may be corrected when jamming bullet into lands. jumping bullets with small runout(.001-.002 thous) might self-correct as the neck lets go. the influence of runout in short bearing surface bullets versus long bearing surface ones and accuracy is an interesting topic which hasn't a lot of discussion. anecdotal observation abound, but a true scientific evaluation would be interesting.

Looks like I will go with a Wilson Seater Die and a Sinclair Concentricity Guage just to check!

Thanks, Dennis
