they ain't fancy but they are repeatable and that's close enough, for most of what we do.
I got 3-k lbs of one huge batch of alloy I have no clue what's in it besides some tin and antimony and lead.
I'm not even 100% sure of it's bhn.
but it shoots in all of my guns just fine and I know I need to add this or that at this or that % to make it work in certain calibers.
I'm fine with that...
