What gives with the weight of some newly aquired lead

[plinker]

FWIW a .490 ball changes about 1 grain for every .001 inch it is bigger or smaller than .490. Yours are dropping about .005 less than .490 so I would expect them to weigh about 172 grains. (OK, I went through the math and it calculates out to 171.6 grains.) It looks like they are right where you would expect for pure lead.

You are spot on. :thumbsup: They shoot well (for my needs) and they are easy to melt down. So my plan is Melt, pour, load, shoot, Recover from the target box and Repeat.

Thanks for your endeavors. :hatsoff:
