Nordnecker, streamlining the "carry items" in one reason I like the simple use of overshot "thin" cards that used to be called BB wads or cards.
I think Track calls the thin cards, "B" wads.
The "A" wad is 1/8" thick. That is the normal over/powder wad, then goes the "C" fiber wad, then shot, then the shot, then the "B" .0625"(1/16") wad.
In the 11 bore, I used 3 of the "B" wads between powder and shot, then a single "B" over this.
For hunting, this system, if it patterns OK in your gun, negates the need for lubricant at least for 5-10 shots or so. Whatever your needs are, as long as they are met.
In the choked gun, I can use this system of wads, only the "B"s or, if I want even tighter patterns, I use the standard 'shotshell' type of wad column of multiple different wads.
