12ga Slug Brinell Harness for Different Velocities?
Hello Everyone! New member here.
I am new to casting and have everything that I need to start this great skill set.
My question is, what is the ideal Brinell hardness for 12ga slugs?
Should it be different for different velocities (ie. subsonic versus 1200 - 1600 fps versus 1600+ fps)?
I have:
20# of Antimonial Lead (RotoMetals)
10# of Foundry (RotoMetals)
50# of Lino and Mono (auction site)
5gal bucket full of WW's
Not sure if it matters, but I'll be shooting a semi-auto 12ga, and I also powder coat with Prismatic Powders.
Thanks in advance for your time and knowledge!
Choke Constrictions listed for different lead & Non-Lead materials.

Poor quality shotgun OR to tight of a choke?

Choke Constrictions listed for different lead & Non-Lead materials.
Lead .031"
Non-Lead .005"
For both, Less is better. Maximums listed.
Basic- the harder the alloy, less constriction wanted.
