I used 32 or 33 one shot cadwelds and it was still cheaper than 
purchasing the mold and equipment. I think the "break even" point is 
some where between 50 and 100, but prices have changed so I'm not sure 
where it'd be today.

Jim mentioned the igniter charge in his was mixed in with the regular 
charge during shipment.  The igniter charge is packed into the cap and 
is of a much finer consistency than the actual charge. I get mixed in 
shipment it must have endured some VERY rough handling as you usually 
have to "tap" the cap on the top of the container to put the igniter 
into the V shaped cone that leads the starting fire into the main 
charge.  There are ways to ignite a charge without the igniter, but they 
take experience working with the stuff so I'll not go into that here.
