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!

Hodgdon has a few 1 oz loads.

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.

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

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

Thank you. This is exactly the kind of info I've been looking for.

Dave,

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