    I did some experimenting with OAL with the Dardas 150gr LSWC bullets in .452 I had made loads in the past, and had some FTF problems, but I don't remember (and can't seem to find) what OAL I used.

    So I made up batches of 25 with OAL of 1.255, 1.260, 1.265, and 1.275 (and remembered to write down the value on the Redding seater, so I can reproduce them) The good news is, they all fed fine in my 1911, without any stoppages. I was using mixed fired 45 brass with Wolf LP primers (left over from the last Great Primer Shortage, when it was all I could get) and Bullseye 6.5 gr.

    I was shooting more for function that accuracy today, and it was cold and hard to concentrate, so I don't have any strong sense that one load shot better than the other.

    What is my next best move to optimize this load? Should I make up 100 at each OAL to make sure they all feed properly? Should a longer OAL in theory be more accurate? Would I want to confirm perfect feeding at a given OAL before I start varying the powder charge, looking for optimal accuracy?

    Thanks for any advice.
