It was designed for super light 12 Ga. loads with light payloads.
It tops out in pressures way before Bullseye and Red Dot data
in the 12 Ga. loads.
Due to the low speeds with the larger payloads vs the pressures
I passed on getting this powder for my shotgun loading, even
though I shot a lot of 7/8 oz. target loads.
If you use it in pistol loads, just follow the loading data carefully.
This is not a powder I would want to test without data due to
the pressures involved.
Good loading.
