Quote from: troglodyte on May 09, 2024, 06:47 PMMy experience is that I require slightly less propellant to achieve book velocities for cast when powder coating. Have to assume the stuff is slidier than raw lead.

Are you certain about this, the powder coating reduces friction substantially, the reduced friction = less pressure, the less pressure = reduced velocity. I have found that you need more propellant to get same velocity via raising the pressures. Then because of the lower pressure you can raise the load to achieve higher velocity than uncoated.
You can at a point move to an faster propellant and step a level up in velocity. This has all been learn back in the Moly and other coating start out days.

In fact, they are so soft that it's in fact almost pure 100% Lead. Because it's not really an alloy, it casts with great difficulty and does not flow as well as the crimp-on wheelwreights. You also would want to increase the temperature a lot to effectively cast a nice bullet without wrinkles. They made great roundballs and I use them exclusively to cast my .715" and .735" roundballs. These balls consume huge amounts of lead, being 550 and 650 grains respectively.*******************************
