Jim,

From looking at your target your doing it right, it's working for you.

These photo's I posted are bullets a friend send me from down south to see why he was getting to many dirt diggers and he instructed me how to load them and use the components he send me with the cup .50 cal bullets.
The problem I saw that caused what I seen on the bullets were a couple things I myself have done.
Bullet to soft,
Wads to flexible,
Nor enough support between the bullet base in the cup between it and the wad.
I went through this myself with the bullets for the .40-70 and .45-120/3-1/4.
If you look at this cropped bullet picture, look at the skirt rim. Those rims were .072" wide and they ended up as a sharp edge from the wads getting pushed into the cup from lack of support of a twisted tail holding the wad from flexing into the cup.
I had read some of the old books why the Sharps rifle company used the twisted tail and why the the cup base in the first place. What they said the cup was supposed to push the hard cast bullet bases out like a mini ball to seal the gas.
I cant remember who wrote that book but I read it in the Library of Congress collections.
