20ga slug question

[hatcreek]

Hi all, I'm planning on loading 20ga slugs, SPW wads in cheddie hulls 2 3/4, with a cheddie 209 primer, I would like to use WSF powder since i have so much of it, any load info would be great. thanks. Oh yes I'm loading a .44cal 255gr hand cast bullet in the sabot. thanks again

Oh yes I'm using a .44cal 255gr hand cast bullet, to put in the sabot. thanks

Hodgdon does list 7/8-oz. lead bird shot load data for Winchester AA and Remington STS type 2-3/4" hulls using WSF powder. All the charges are between 16.5 and 17.5 grains with multiple primers and wads listed.

7/8-oz. is approximately 383-grains. So based on that you could probably safely start out with about 18 grains of powder and work it up a little. You should probably be able to safely get up to 20+ grains. I would work slow in single grain increments in a heavily built strong single shot break action type gun using it as a test platform (think 20ga. NEF-USH) until I got sticky extraction (that is the first pressure sign you will usually get with the type of hulls you are using) and then back off a grain or two and call it good.

Can't help you more then that since I've only worked with WSF powder for slug loads in the larger 12ga.

Thank you Turbo, I'll give it a try and let you know.
