Jim,
The biggest thing that I need to stress, regarding LSWC in the 1911/1911A1 platform, is the barrel throat.
In the picture below (not my pic, I 'borrowed it' from the 'net), the barrel throat/chamber on the LEFT is throated for WC or LSWC boolits. I refer to it as a "C" on it's back.
The barrel throat/chamber shown on the right, is set up for "hardball" or RN boolits. (Note how the throat is shaped like a "U".)
IF your barrel is throated this way, you MAY (more than likely) have problems feeding/chambering WC loads in your pistol.
I need to check, but I did cycle some of the dummy SWCs in my RO, seemed to work as is.
Unless you have some of those 'new-fangled' small primer .45 acp cases, your small pistol primers ain't gonna work. You need LP primers for .45 acp.
The SP primers are for the 9mm I picked up a few weeks ago. I have Winchester LP primers in stock already.
