29 degrees, but no rain! Melt some lead!

I chose the 45-270-SAA mold today, because it's big and holds lots of heat, and because I'm low on .45s. 
This is 13 pounds of em. ('should be about 325 of em, by weight)
'Don't look like much, but that's all I could stand. That North wind was blowing right straight into my ear.
(I cast out in my yard). At least I got a little casting done and that scratched my itch for today.
I haven't weighed any, but they drop at .4535
I believe they are supposed to weigh around 280gr. but I'll weigh some after lubing. The alloy is 90% pure, with 8%WW and 2% tin. They need to be soft, because my Peacemaker ain't gonna be pushin' em all that fast.
They were poured mostly at 730 degrees, or as close as I could keep it.

Just for kicks and grins I plugged some numbers into the calculator Bumpo put up. I use a hundred pound ratio to keep it simple for me, it's still early. I came up with the following,
Tin=2.04%
Antimony=0.24%
Arsenic=0.02%
Pure Lead=97.7%
Total Weight=100.0#
Est. Hardness=9.4 BHN
If your alloy is remotely close to this you should see some fair expansion if your loading to the range of 850-950 FPS. I typically run mine in the mid to upper 900fps range using my alloy and it runs in the 10.5 BHN range.
Below left is the 270 SAA poured from my alloy,
This is the write up I did on it as well,
Pouring HP's and Learning to Blend Alloy's.
Your on the right track, now get out there and burn some powder man, you can't keep that thing all nice and new forever, soot it up for peat sake.
