Hi, a few months ago I found a chart on this forum that gave length and weight for .187 cores to make 22rimife jackets.

I can't locate this chart now

If anyone is familiar could you please share this info please?

There is one in the Swaging stickies giving a little more detail. "A little Math will Hopefully be helpful."

The Corbin Link in post #2 provides the "Math" and application to the diameter/length/weight at the top of the page.
