I had pretty good luck getting 230 grain cast lead ball from Grand Master Bullets in Colorado, when I couldn't get the Blue lube bullets here locally. I have noticed he has several weights in a .452" for your shooting pleasures. 1.20" seems to be the length both mine and my wifes 1911's prefer.
GMB was fairly priced and shipped out quick and also will do phone orders
Howdy Rooster, just checked out there web site, looks like they're closed for now, here is what they posted.
Notice:
Due to fire, we experienced a total loss of our personal dwelling.
Due to these circumstances, We are NOT taking any orders for a short period.
We hope to be back on our feet as soon as possible - please check back often.
If you have any questions or want to be notified when we are up again - email us grandmasterbullets@yahoo.com
Thank you for your kind thoughts and patience.
