OK Sgt.
I tested the range lead these 121 bullets were cast with and they test 8.2 on the lee tester. For comparison the way the Lee is set it tests the same as my 1/16 Tin/Lead. As gray as these are I think there is a lot of WW in that scrape.
Here are the recovered 121's I think the two missing must have blown through the pile.
The top two were shot with the .45-70 Shiloh and the bottom two with the .45-90 Shiloh. The camera did not pick this up to good but the third from the top is the .45-90 and it has a little gas cut and it shows slight stripping also the bottom bullet has a increased land when it got slammed into the throat from the large jump but the top shot in the m70 does not look much better. It's hard to see in the picture.
