Thread: Bullet casting

The correct hardness lead, read on the inter web, depends on fps, gas checks to stop erosion, damage to the bottom of the projectile, you'll need the correct mould that you can fit gas checks to, rebate on base of projectile. Learn to flux the molten lead to remove impurities, beeswax will flux. Do it outside or well ventilated space because you don't want to suck the fumes, you can light the fumes from the fluxing. Heat your mould to get a good finish to the projectile, carbon the inside of your mould for good release of the moulded projectile from the mould, I use a cast iron pot on an LPG burner to break big quantities of lead into ingots for my Lee pot. Modify the plunger pin by replacing with a bigger dia rod with the ends machined to match the original, better sealing of the outlet with a bit more weight. Pour the lead from the pot into the mould with an air gap, if you put the mould up to the nipple the air in the mould can't escape and can pressurize the mould putting whiskers on the projectile. Hope that load of shit helps a little
