In our research to find economical and easy to use setups to load
various slug/sabot combos in 12, 20 and other gauges, you've
seen what we are doing with 58cal slugs in 12ga accutip type sabot we
are getting built, and 58cal slugs in 20ga BPI Commander shotwad.
You've seen pics of group shot by Ajay 58cal in 20ga Commander wad.
And Greg Sappington made 16ga HP slug that fit 12ga BPI CSD wad.
CSD wads are little thicker. In that vein we found another 20 ga combo
that uses the BPI 20ga CSD wads and larger diameter of the 54cal
muzzleloading slugs. Wad is thick and short so we can get the
volumne of our slow powder we want in the loads for higher speeds.
And base of CSD 20ga wad is thicker and stronger than most wads.
. It doesn't have built on cushion, doesn't need cushion, which is not
needed for slow powder loads. Has a good built on powder seal.
It is long so it can be cut to fit any 54cal slug length.
Best 54cal slugs to use are .543" and up.
There is .548" Sharps style 2nd in picture from Dixie Gunworks.There is
54cal Great Plains in picture on left, Far right in picture is 550 Magnum
jacketed bullets in 20ga CSD. Great for hogs, bear. There are a variety
of 54cal slugs you can cast or buy. Not big number like 58cal, but enough
to find good simple combo. Shot 3" group with 54cal Great Plains in
CSD at 30 yds, smooth bore. 380gr going over 2000 fps.
Second picture shows they even work and fit good in 20ga RMC brass.
Fits in a brass case real tight with .548" Sharps style slug in picture..

Third picture shows how we mono-block 585HE barrels into strong
singleshot break actions. Done it in NEFs, CBCs, Pedretti, Beretta,
and the Magtech 199 shown above.

Fourth picture is the O/U Tristar with 585HE on top and 3.5" 12ga bottom.
We sleeved the top barrel with .585" ID sleeve. We will use it with
the 58cal .585" Minie hollowbase slugs. Bottom just for shot loads
with a interchangeable chokes. Ed
