Everywhere it says out of stock. I worte to Speer but no answer to this. Does anyone know the story on these? They work the best for my marlin 35
That would be the wrong assumption. Speer stated in #9 (published in 1974) that they had started using SAAMI pressure testing equipment - previously they used primer appearance, etc. So prior to that time they had no idea of the actual pressures of their loads. Current data is lower because that previous data was found to be over the SAAMI maximum pressure. Since Speer is a member of SAAMI they reduced the charges to be compliant. No conspiracies, lawyers or lawsuits required, just science.…(This load is from Speer Reloading Data #7 from back in the 70's.
