Re: help please on dummy round info.
To get exactly what you want, wait on the brass, bullets, and dies. Don't order the dies "that might work". Order the dies that will work. Assemble as many as 3 or 4 to your specs and then send them to your 'smith along with your magazine length requirments. Wrap your dumbies carefully, so the bullets don't get 'pushed back' during transit/handling.
"Shoots real good!": definition; it didn't blow-up in my face.
