Don I'm not saying not to size the cases I size some for some of my shooting. What I'm getting at is the wad should fit tight in the fired case so when it is fired the case neck expands in the chamber and if a wad fits loose in a fired case the gas will seep past the wad before the bullet expands fitting the bore and gas cuts happen shooting a PP bullet. I went through this when I first started loading PP with out a lube wad just using a plastic wad under the bullet and the chamber was a little loose where the wad seated easy in a unseized and the accuracy never showed up with the ladder loads, I had a bunch of flyers and lead when cleaning. When using the same rifle I added a thin 1/16" cork wad under the bullet and the plastic over the powder the accuracy was there and the lead was gone. This made me do the snow thing when it came I loaded some with just a plastic wad and this is what I found.

Size your cases if you feel the need too but getting the right diameter wad is a plus or using a soft expandable wad that seal fast and the unexplained vertical will disappear.
