Sorry Joe, I thought after you reread it it would be apparent. 
You start with "Not true.  Find the load that gives best accuracy."
  
So it is OK to have an air gap.

Then you said  "Have a friend who's best load in his 32/40 W is thirty grains BP.  I use forty because I don't size my brass. The bullet sits on top of the powder. and A large airspace in any BP firearm is bad.  Like pushing a ball/bullet half way down the barrel then firing it." 

So don't have an airspace. 

Bullet is in front of the case, it never touches the brass. BS Black is the only place I use a wad, have to, otherwise powder spills on loading

Think your contradiction was that you say an air-gap is OK, then say a large air-gap is bad. Guess there are air-gaps and air-gaps. Smaller ones, say up to 3/8", are OK, but large ones, say 1/2"+, are bad. Whatever, I shoot a long enough bullet that in my 38cal it is is essentially breech-seated while still being about 1/8" into the case mouth sitting on the wad.

All this begs another question. A couple of you state you are shooting BP with the bullet right on the powder. Are you shooting plain-base cast bullets with BP and no wad?
