Anyone else doing this with your cast Boolits? I know I am still new to this and some of this is being done just out of curiosity. One observation is that I'm not sure if it is the quality of the mold or if I am just improving technic! I have been weigh checking all along and sorting into groups for loading purposes. As I am progressing my weights are becoming much more consistent.
This last batch that I just cast yesterday are from a Lyman single cavity 452374 225gr RN. Ended up with 103 pcs. I cast some of these previously but I had the wrong handles and the blocks were not closing properly and they were all oversize and way over weight. I received the proper handles and WoW what a difference.
With this batch I found the median weight with this alloy for this mold was dropping at 228gr which I thought was very good. So as I was sorting these I set my parameters to +/- 0.3gr of the 228gr and ended with 70within this range and 10 pcs under the -3gr and 23 pcs over the +.3gr.. I didn't weigh for total variance but I believe it is less than 1.0gr +/-.
So again this is telling me that either I am getting better and more consistent or the iron mold is more consistent than the Aluminum. I'm hoping it's the case that I'm improving.
