I am currently shooting berry 220 gr copper coated bullets along with 10.6gr of H4198 for a subsonic load in 300 AAC.
Plan on casting 230gr soon in LEE mold then powder coating with Smokes black
My first thought is low velocity load so Brinnell of 12 (wheelweights) would be plenty but after reading more I see this little load will produce pressure around 20,000 and hardness needs to be higher.
I have plenty of linotype, magnum shot, tin, wheelweight ingots.....just need help figuring out what hardness to make boolitz.
My current thought is half ww half linotype and water quench....just a WAG on my part though...I do not want dem boolitz ANY harder than they need to be.
HELP
