I just bought an impact puller and pulled some mistake rounds. To empty the puller, I just dumped it into a party cup, and consequently it came into contact with the lube on the lead bullets (unknown composition of both).

I've heard that bullet lube is detrimental to powder, so is it advisable to just destroy this powder? Especially since there is not much there, only about 6 rounds worth.

I'm sure some will disagree with me but I personally would never recycle powder just in case it has been contaminated.

Cost is pretty insignificant and quite honestly you can have a lot of fun with old powder anyway. I usually used mine to burn out ant or termite nests....... just tip a teaspoon or so into each hole and then touch it off with as match or lighted cigarette....... do it at dusk or after dark and the fireworks can be a bit of added fun as well........ Oh and it's the most effective ant killer you'll ever come across.

I have pulled bullets from hundreds if not thousands of rounds of ammo.

I always recycle the powder unless the lube was damp and made the powder sticky there nothing to worry about.

The "contaminated" powder is that which sticks to the bullets. If it doesn't stick, it isn't contaminated. Carefully pick the bullets out of the powder and the remaining powder in the container should be fairly clean. I wouldn't necessarily use it in benchrest-quality ammunition intended for thousand-yard matches, but if it is for most types of handgun shooting it should be fine.

Thanks for the replies, I think I'll salvage it. Powder's a bit hard to locate right now.
