Homasote

[Fiftyfour]

Has anyone used homasote for making wads?

[Joe S.]

No but we use it under prefab wood burning fireplaces.Pretty tough stuff,might work but in my mind you will need to fabricate some sort to cutter to make the wads,very dense.Perhaps try micore,its kinda like acoustic tile like material only fire retardant.Probable a little easier to work with,maybe not tough enough though.

DonaCona is what is normally used.  I just buy them from Track.

That's funny. My dad works for Homasote. No idea if it would work

Using a 5/8 hollow punch, I made a few and split them  to be about 1\8 inch thick. They were snug in the 20 gauge and lubricated with Crisco.
Used 80 grains of 2f and 1.2 ounces of #5 lead shot with  another piece on top.  Pattern was not that impressive at 30 yards. Only tried a couple shots.

Try a card under, then the 1/8"  homosote, then shot, then thin card over shot.

Some guys, in cylinder bores, shoot a couple thin "B" wads over the powder, then shot then 1 thin card. They figure the thin, light over-shot cards

lack the weight and energy to disrupt the shot cloud like heavier wads do.  Photos prove heavy wads blast into the rear of the shot cloud which causes huge holes in patterns - 1910  by W.W. Greener.
