Something else that occurred to me when considering "What would Jedidiah do?" as regards to casting. I bet in 1760 they weren't using scrap plumber's lead and reclaimed crusty pipe like I am. I get more dross than lead when I melt down my free scrap. Solder, okum, calcium carbinate, dried poo . . . you name it.
Part of why I weigh and inspect is because I'm skeptical of my own skills. I know the first 10 balls will be from a cold mould and wrinkled, then occasional voids as I allow the mould to cool too long between pours or when I slop a pour and see the sprue suck in as it cools (a visual sign you have a possible void). I keep +/- 0.4 grains or so. Enough to float the bar on my balance scale.
Back to the original queston: I like cast balls better because it is fun and rewarding to roll my own. Taking a buck with a ball you cast yourself is a feeling that can't be bought. But if I had to shoot a shotglass off my dog's head at 50 yards I'd probably choose a swaged ball to try it. :winking: I'd use a cast ball if it was my neighbor's noisy cur. :haha:
