A little insight on these.

Lately it appears manufacturers have moved to iron as a weight additive from zinc powder. Zinc in some jurisdictions comes up on soil analysis and can be considered an unacceptable contaminant, whereas iron is a natural appearing substance in soil, even in higher quantities and gets disregarded if soil remediation is a requirement for resale of lands.

I am not a fan of iron as an additive because its typically harder than the feedpath its being shot through and if used extensively you will notice scoring on the inside of you barrel - a steel wool effect. Zinc was softer and finer and did not do this. It also prematurely wears your feedpath. Iron also makes double polish almost impossible as the iron on the surface does not bond well with the ABS or PLA and literally falls out, leaving pitting, no matter how much polishing you do.

We sell this in our Frag line of product (0.36g) as I don't consider it to be suitable to sell as a premium line. The greens and yellows are still the higher quality material (manufacturing not withstanding) if you can find them but most manufacturers seem to be on this iron trend. I believe its cheaper and easier to do weight control all the way up to .43g. If you see a black BB above .32g its most likely because of this additive.

The reason it cleans up in coke is that the iron isn't as fine and they aren't washing the BBs prior to packaging - this is on purpose because the fine dust left in your feedpath "acts as a lubricant" for the BB (sarcasm). Throw a nail into a glass of coke and leave it for a week - its a great metal cleaner.

If you're running a tuned gun with a tightbore you might experience mid to long term issues. Ultimately this material will gum your system up - it is fine enough to eventually get into the mechbox lubricant, turning into liquid sandpaper and potentially prematurely wearing your internals. Again, this takes a fair amount of use of the product, but once its in the mechbox and in the lubricant, it won't matter if you stop using an iron additive BB, it will continue to wear. Clean and relube your mechbox. A rule of thumb to follow is that there should *never* be a powder residue on a BB product and if someone tells you its for lubricant, its more likely a lack of cleaning in post production.

This is why BB Bastard has been shy on the heavyweights this year and only has .36g in the frag line. If I can't be sure it won't damage your gun, I prefer not to sell it.

Good review though, nice to see some pictures.
