Hi, I have some hollow point cast bullets in 215gr .452 diameter for use in my 1911 in 45 acp . I later discovered that these bullets are 10 BHN. This makes for quite a soft bullet. In Richard Lee's Modern Reloading Second Edition, Richard goes to some trouble to explain that the pressure (and not the velocity) is what will cause the lead bullet to deform too much and become inaccurate at higher pressures. Also of course, cause other issues. He provides a chart (for lead rifle loads) that identifies the neighborhood of pressure one should shoot for for maximum accuracy with bullet of various BHN. In my case, I will be willing to do the work, and work up a proper load as per usual. The only question I have is whether it is best to use a fast burning powder (like WST for example), or a slower burning powder (Longshot as an example) to keep the pressure down and still achieve an accurate and usable load in the end with a bullet this soft. It seems like a lot of people use fast burning powders with lead, and this seems to conflict with what I understood from the Lee manual. However, I imagine most of the bullets are made of a harder alloy than this one . What do you think about a powder selection for this soft of a bullet? Thanks!
