I just took a brief glance at notes going back to 1988 when I began working with cast bullets in various 9mm handguns. Over the years, I've tried at least twelve different cast bullet designs ranging in weight from a little over 100 grains to about 160.
As for powders, I've used at least as many as I have bullet designs. Looks like best results overall have been with Bullseye and 231. For some reason, I didn't use Bullseye until I was well into the project.
The best bullet I have found so far has been a 150 grain roundnose design using an obsolete .38 Special Lyman mould, #358212, cast from wheelweight alloy and sized as large as will chamber without difficulty. Don't remember offhand if this is .358" or .359".
With Bullseye powder, this load is quite accurate and 100% reliable in functioning in my three 9mm pistols. Also shoots to point of aim offhand at 25 yards, something lighter bullets may or may not do.
