Importence of the wad stack

[Kurt]

Don.

A long time ago I tried seating some bullets with a lot of runout they where greasers an only a couple looked like they had land cuts higher on the ogive ahead of the front driving band but I don't remember seeing any gas cuts at the base. It's pretty hard to get a PP seated with runout.
I loaded some PP with a hole on the side of the lube wad like a sickle moon seated over a thin poster wad about .012" and the lead went into that void and left a tail like a long wide fin. I don't remember what the mix was anymore. It don't take much to move the bullet base when the powder is set off.
But again the hard alloys are more prone to gas cuts then the soft alloys.
