COAL For SWC

I want to load some 185 gr SWC for my 1911.  I have not loaded this bullet type before except in revolvers. 
Full wadcutters are often loaded flush with the case.  How does one properly load a semi wadcutter?  Or, does it not matter except to the extent a certain OAL may be more or less accurate?

I leave about 1/32" of the should out past the brass. Its not super critical like loading long range rifle rounds, you aren't chasing the lands or anything. If anything some people may tell you the crimp matters more, I crimp to .469", some people will go tighter.

I reload the Dardas 185 gr H&G#130 "button bullet" to a OAL / COAL of anywhere between 1.245-1.260, depending upon which gun or combo of guns that I am loading for. Most people suggest as noted above about  1/32 (.031) above the case mouth which is generally about 1.019 to the shoulder depending upon the case length & about .469-.470 taper crimp.

sjs,  There appears to be an even Bazillion different molds for 45 SWC bullets. So instead of trying for an OAL most of us have agreed on about a fingernail (ok, 1/32") of lead protruding from the case and then ignoring OAL. This works not only for accuracy but function. I crimp tighter then some but that is the way I learned it. I have also got big fingernails This picture shows a SWC loaded by me the way I do it.

Thanks, that is what I needed to know.

Once you load a few, take the time to remove the barrel from your 1911 and do a drop test to see how the cartridge fits in the chamber.  It should be flush with the end of the hood of the barrel.
