Hi all,
I'm looking for the correct COAL for .45 ACP using the Lee TL452-230-TC tumble lube bullet.
I have examined this thread here:
http://forum.m1911.org/archive/index.php/t-92703.html
And this spreadsheet here:
https://docs.google.com/spreadsheet/ccc?key=0AjwkIDKAo3ckdGU5Qk1ERHVVdnhrYmJLaGpCbS1lOFE&hl=en#gid=0
And based on these I figure a COAL of 1.210
However, even when I seat at 1.185, and I drop the bullet into the chamber of my P90 barrel, it sticks, and when I remove it, there is a tiny ring around the shoulder of the bullet nose, which tells me I am bottoming out on lead and not the case mouth.
In order to get it to just kiss off the case mouth, I have to seat to 1.170.
Should I let my barrel chamber be my guide for setting the bullet depth, such that when I drop it in it can spin freely on the case mouth?
I'm loading with 4.8 grains of Bullseye, FYI.
Nevermind, I found the answer back in one of my old posts here:

grubbylabs found this mold in the Lyman 4th edition with a COAL of 1.170, an that is just about exactly right from what I am measuring.
