It wasn’t a “reduced” load, it was a Trapdoor load listed in the Lyman 46th and 49th Editions. The 46th addition used to call out for fillers with some loads and this load did not have a call out for one. Each load is dipped, put on a scale, and trickled up to the exact amount desired. It was 38.0g of 3031, and as I stated, it was a one time failure. For me, once was enough. There are simply too many excellent powders to be used that shoot just as well or better.Could the 3031 melt down be a result of too much unused case capacity? Was it a reduced load?
