I'm trying to cut cost anywhere i can and seen Missouri bullet company offers coated lead and I'm pretty sure Mr. Walkalong has recommended them to me several times. .
My main concern is damage to the firearm/leading, accuracy and ease of use.
If you want to cut cost anywhere you can, learn how to cast bullets and powder coat them yourself.
With lead fairly easily obtainable at $1/pound, a 120g 9mm bullet costs 1.7 cents and a 240g .44 bullet will cost 3.4 cents so the total cost per shot regardless of handgun caliber will be almost the same within a couple of pennies.
Once you get a melter which can be as simple as a cast iron pot on a thrift store Coleman gas stove or a "fancy" Lee 4-20 bottom pour pot @ $70, a $40 6-cavity mold will pay for itself in savings over commercial cast bullets with the first 500-1000 rounds.
A $5 thrift store toaster oven is typically the only "equipment" you need to buy to start powder coating. A teaspoon of $5/pound bottle of harbor Freight red powder will coat about 100 bullets. 20 minutes at about 400F and they're done.
I size my 45ACP bullets to 0.451 with the Lee push through sizer and load them up WITH the 45ACP FCD in the final stage of my LnL AP.
I used to be fearful of swaging down lead bullets with the FCD so I replaced them with the Lee taper crimp die. Recently, I've been doing tests by shooting PC bullets that were run through the FCD. The soot between the lands was just that, soot. Here are some pics after 400 PC bullets loaded using the FCD through my M&P 40 barrel followed by a single pass with a wadded up piece of paper towel.
After this I do use a patch dampened with CLP or Hoppes No9 but there is no leading at all, just soot.
