Re: 4 bore ball size - sorry should have posted here initial

Yogi, I just weighed the one 1.025 ball in the almost-wheel weight alloy I sent you that I have left and got 1563 grains (it was sized to 1.007"). I think most of them weighed 1570-1580 grains, as I wasn't too picky about getting perfect zero-wrinkle bullets. Close enough for our purposes, I figured.

I weighed 6 unsized pure lead 1.025" balls (with a sprue flat) and got a range of 1602-1608 with an average of 1605.

Despite heating the mold, high casting temp, etc, with my bottom pour pot it takes long enough to fill the mold that a few cold spots seem just about inevitable. On my to-do list is getting a second pot and drilling out the spout and making a larger rod to get a higher flow rate. I've tried using a laddle many times, but the results weren't better enough for the extra effort. By no means am I a casting expert, so I usually shoot for good enough rather than perfect bullets for my own practice.
