Thanks for the comments guys. Jim, 13/16 does make some sense, but actually the 3/4 oz load in the 28 is balistically more similar to the 1 oz load in the 20, not the 7/8 oz load. The 24 gage 7/8 oz load is almost perfectly proportioned to the 1 oz 20. But we are kind of splitting hairs with these small gauges.

Mr. Hall, I have thought about those brass hulls available out there. The modern ones do generally need bigger wads as the walls are so thin. I could get bigger wads from Circle Fly. I load the 16 gauge brass shells from MagTech and from Hammer Double in AZ http://www.hammerdouble.com. They recommend 14 gauge card wads and fillers, and 13 gauge overshot wads, and that's what I use. I have 5000 old Federal 16 gauge shot cups (that's right, the shot cup only, remember those?) and I'll use them if I want to protect the shot a little better. Anyway, Hammer Double sells the same brass as as MagTech, but MagTech's use large pistol primers and Hammer Double modifies the case for 209 primers. This is a bigger deal than you might think, as they insert a plastic base wad similar to the ones found in Fiocchi Reiffenhauser cases, so the powder sits no lower than the hot end of the primer -- helps ignition I guess. I have done a crude side by side test (no pun intended) of both these brass cases, with fast and slow smokeless powders (Red Dot and HS-6), and couldn't tell much difference. Pretty non-quantitative test, so it isn't worth much, but the loads sounded good and broke targets. Maybe I'll get quantitative later. I modified the deprime punch and reprime station of a MEC 600 to handle the large pistol primers.....more lathe work. Anyway, you're right that brass cases in 24 gauge would be practical and maybe even economical in the long run. They are only about 2 3/8 inches long, so they don't have a lot more capacity than a 2 9/16 in Fiocchi (65 mm).

John -- I have not talked to Fiocchi, but I shoot their shells. Their 24's are all 65 mm, same as the new primed empties available from BPI. BPI also sells these factory loaded Fiocchi 24's, of course. I don't like them much. They shoot OK, but puff out a pile of smoke. They use a sort of spreader wad and pattern kinda loose, and they only have an 11/16 oz load. They really lead up my barrels. I probably won't buy any more now.

Best Regards,
Tony Lowe
