What would be the chance that the use of a soft aluminum for pellets or slugs? Just a thought for another alternative to lead.

Unless of course you want to help out the false advertising on half the break barrel speeds out there using a light alloy

Lead is relatively cheap. Lead expands quite well. Lead is relatively heavy. Lead can be easily formed into a variety of shapes.
I suppose if you don't eat the lead or get it into molten form and inhale the fumes you'll probably be just fine.
Shoot lead. Kill varmints. Fish with lead and annihilate the toads

Everytime a Californians shoots lead into the dirt, our boy Gavin sheds a single tear. I best buy an sk-19 and up my pellet count per day.

A few reasons why the use of aluminum is unlikely:
- Aluminum is harder than lead, but also than tin and zinc, which are already lead-free substitute materials. An Aluminium projectile wouldn't engage the rifling properly (if at all).
- Current production equipment (swaging machines) could not deform Aluminium easily, and turning would be very expensive
- In addition, the barrel wear would be increased immensely.
- Hollow point bullets for hunting would not mushroom.
- The penetration capabilities would make it suspicious to our law makers (just a personal thought...).
- Because of the much lower density and the associated higher speed, the twist rates of the current barrels would not fit, and the projectiles would easily get supersonic.
Just my two cents...

Interesting. Tin melts at a much lower temperature than lead.
There is a thread on casting tin pellets here. This seems allot more interesting than casting lead.

I guess there are some with an alloy of bismuth,Antimony and tin also.
