What would a standard 12 gauge load be? About 1 oz of shot? What powder charge is a good starting point for 1 oz of shot?
vanstg: 1 oz is on the bottom end of the black powder load scale for a 12 gauge, the shot ranges from 1 ounce to 1 1/2 ounce loads...
Also the powder drams (I will give grains as well) range from 2 3/4 drams (75 grains) all the way up to 3 3/4 drams (102 grains) of FFg black powder
The wads look like this...
Over powder card /over shot cards:
1/2 inch fiber wad:
A good starting load is as follows, in order of loading...
(Light field load)
2 3/4 drams (75 grains) FFg
One heavy (.125 inch thick) over powder card
One 1/2 inch fiber wad (lubed)
1 onces of chilled shot (any shot size will work)
One thin overshot card (to hold it all in place)
This load gives 1103 fps and 1181 FT/lbs. muzzle energy...
(Field load)
3 1/4 drams (89 grains) FFg
One heavy (.125 inch thick) over powder card
One 1/2 inch fiber wad (lubed)
1 1/8 onces of chilled shot
One thin overshot card
This load gives 1220 fps and 1624 FT/lbs. muzzle energy...
(Heavy field load)
3 1/2 drams (96 grains) FFg
One heavy (.125 inch thick) over powder card
One 1/2 inch fiber wad (lubed)

One thin overshot card
This load gives 1231 fps and 1838 FT/lbs. muzzle energy...
(Extra-Heavy field load)
3 3/4 drams (102 grains) FFg
One heavy (.125 inch thick) over powder card
One 1/2 inch fiber wad (lubed)
1 1/2 onces of chilled shot
One thin overshot card
