Well i was trying a couple different things at the same time today after recieving the twinjector. Not being use to this piece of equiptment i shot the first round out the bottom of the clamped mold because i accidently pushed to hard when trying to inject it. I also was trying some sample packs of mica powder i picked up at walmart yesterday since i had never used any. As far as color match goes i got really close to the red in berkley power worms red shad by using the mica powder. I never tried swirling again though, but will.
