Swim jig. Are you using lead molds? Thats the only size inbetween but its such a weird one.
"Lead free, guilt free"
Lead mold only means that the weights it is rated for are for with the use of lead. People aren't making tin/bismuth molds just because a couple states banned lead. Therefore you use lead molds and the end product is lighter than it should be, no biggy. Lead has a melting point higher than tin/bismuth therefore you can use them.
