Started reloading for my new SA Loaded 1911. I understand that the 45 acp headspaces off of the case mouth. I cast some LEE 452-228 228gr RN bullets this evening. Could not find specific data for this round in regards to COAL. There were other similar rounds recommending between 1.250 - 1.272.
So I took my barrel out of my 1911 and started experimenting with different over-all lengths. The ogive contacted the rifling on everything above 1.210. Once I seated to 1.210 the case mouth struck first. So my question is am I checking this incorrectly or do I really need to seat these at 1.210? Does the case mouth NEED to contact the lip of the rifling to operate correctly? Is it safe to headspace off of the bullet?
I am worried about finding a safe starting powder load (cannot find a similar bullet shape that is seated this far). Any help is appreciated!
