I have a couple loads, that I had tested by Tom Armbrust.


New 2-1/2" Cheddite hull. Can be purchased from Graff's and sons.
It comes primed with Cheddite primer, but you can use Win. 209 after.
20 grains International Clays
GU-1222 wad. can also get from Graff's.
1 oz. lead shot
1200 FPS @ 6800 PSI
If you adjust your reloader correctly, you'll get perfect crimps,
with either 6 or 8 point crimp.

You can also use:
21 grains of IMR-PB for 1125 FPS @ 6000 PSI
22 grains of IMR-PB for 1225 FPS @ 7200 PSI
These loads were also tested.
Regards, Dave

If your loading 2-3/4" hulls, you can use the same load data listed above, except use the GU-1225 wad. Pressure and velocity will be the same.
