Default 12 guage 2 1/2 data

Does anyone have any good data for 2 1/2 inch 12 guage. I have never loaded them before and am looking for something to duplicate RST ballistics. This is for a damascus GH in good shootable condition. Thanks!

I would love to find some data for 2 1/2" as well. Ideally I would like to find something in the 5000-6500 psi range. Does anyone know if Sherman Bell did an article on low pressure 2 1/2" loads?

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

Opps, I guess they're out of stock right now.

But, you can cut down the 2-3/4" Cheddite hulls.

Dave,

Any reason to think these numbers would be radically different substituting bismuth for the lead??
