I just ordered speer number 8 from Amazon. Hopefully there will be some new info for me in there. They seem to recommend different powders than Hornady and nosler and hodgdon, which I already have
Watch out. I'm not saying No.8 is for sure the one with the problem, but one of the older Speer manuals had data developed with incorrect calibration of the copper slugs for the pressure gun. As a result some rather hot loads were published.
