Casting projectiles for best accuracy results

Muzzle loaders , unlike cartridge rifles , use pure lead bullets/balls , so no wheel weights or solder in the melt pot .

Use a thermostatically controlled melt pot to keep temperatures the same , flux the molten lead with beeswax .

Use a steel mould , alloy moulds change size as they heat up and cool down.
Over fill your mould in one continuous pour so there is a large sprue casting to be cut off , this helps stop the formation of air bubbles ., if the sprue casting slumps in the middle it can indicate a air pocket.

Weigh all your cast projectiles when cold ,and separate into 1 grain difference lots . all those spot on expected weight are used for hunting and target shooting , those  1 grain less than the expected weight could be used for plinking , all those under weight should be discarded and re melted .

commercially swaged balls also need to be sorted by weight as experience has shown they actually vary in weight more than properly cast pullets .

I am highly allergic to lead fumes so I only use swaged balls.
I recommend the use of a lead fume face mask  or better still a fume cupboard , expensive to make but healthwise worth it .

Always load cast balls with the sprue uppermost , I know one shooter who half covers the bottom of an old time biscuit tin with cast balls , gives them a spray of WD40 and puts them in the boot of his car , the rolling around, evens out the sprue.

If you are going to keep lead projectiles for any time  coat them with WD or a light bees wax, as lead oxidizes it grows slightly in dimension
  

Shooting is the most fun you can legally have with your clothes on .
Proverbs 12:27
The lazy do not roast any game, but the diligent feed on the riches of the hunt.

I do the same with my cast balls... i have some small plastic containers I bought from the dollar shop which i half cover the bottom with balls so they can roll around in as I leave the containers in the boot of my car... over a period time I notice that their beautifully round and the spruce is evened out.
