[QUOTE="Mikecr, post: 1097176, member: 1521"] For every notion in reloading there are qualifiers associated. With straight ammo & neck turning, the qualifier is chamber clearances. Where you have sloppy fitting of heavily FL sized ammo, runout contributes nothing to results. So it could be suggested that loose chambers are a workaround for runout, and I believe this is a reason many seem happier with results from loose chamber fit. Those with tighter clearances could find that runout matters. The reason runout can be detrimental for tighter chambers is chambered tensions created by crooked ammo. It doesn't matter so much where bullets are pointed initially(we'll never know that), but where bullets end up pointed as the banana straightens under early pressure. Chambered tension points are also analogous to other tension points(w/resp to barrel vibrations). Rest a thumb on an action tang mid-string to see what this can do. [/QUOTE]
