Maybe there's a physics major out there who can explain it to us both
casting tool info.

Guys, I think the answer to why bottom pour pots don't perform as well on large bullet pours is actually fairly simple. You just can't get as much lead flowing fast enough to fill the mould, and when pouring with a ladle, in order for me to get a good pour, I tip the mould towards the ladle and then bring the mould back to a level position all the while pouring the lead. You can't tip the mould while using the bottom pour pot, it creates too much of a mess. Randy

Thanks Randy,
I was wondering about that aspect. The opening in the spout of a bottom pour could not be made too big becuase of controling the flow of melt. Whereas one can control the flow from a ladle. Like you, when using a side pour ladle I hold the mould horizontally and marry it to the spout of the dipper and then in one smooth motion bring them quickly to the vertical (naturally with the ladle on top). And you are right, this allows a quicker fill of the mould. I just wasn't sure that is the whole answer.
