More on Cast Bullets
In the continued testing of cast bullet loads for the 9mm Parabellum, one fact was discovered. Certain pistols, regardless of make or model, do not function well with light cast bullet loads. One standard load, functioned in a Berreta Model 92, wartime Walther P.38 (BYF 44), and a wartime Browning Hi Power (Inglis). The load would not function in another wartime P.38 (AC 43). There is no discernible reason for this situation, all the pistols are in excellent mechanical condition and well broken in. I can only assume recoil springs, while within specification, make a difference. Therefore its imperative to test loads in each individual pistol. This is particularly important if a large supply of cast bullet ammunition is going to be manufactured. This procedure also holds true for surplus or remanufactured 9mm ammo. Over the years the specifications for 9mm ammo has varied by country and manufacturer, just enough to cause problems is some pistols. The next round of testing will include striker pistols, namely a P08 Luger and an Astra Model 600.
