I had a chance to try out those Lee bullet loads, and let's say

the accuracy won't send me out to buy a new  mould.  Not horrible, but nothing to brag about.

Also: the second loads that I left to max length?  If there's any fouling in the throat, they won't chamber.  As in "Clean the bore, chamber one, fire it to foul the bore, blow tube, now the next round won't chamber."

So much for that idea.  I'll try seating the bullets a little deeper and see if that works.
