Wayne,
Here is a picture of my H&G #290BB bullet. This is of the design you speak of that is loaded commercially, kinda. It has a shorter nose than the 358429 which is supposed to be similar to the H&G #51 designed by Sharpe. They were originally designed to fit in the "N" frame's shorter cylinder. Something the 358429 doesn't do when seated to the crimp groove, or so I've heard.
As cast, 80% wheel weights, 20% Linotype this bullet weighs about 165gr. I have no leading with this bullet and have driven it to over 1500fps from a Marlin 1894 rifle.
I know that this is more information than you asked for but hey, I got to writing and forgot to stop!
