Anyone know where I can purchase .590 round balls? I'm currently using .595 balls and walmart .015-.018 pillow ticking. All is actually working fine but I'd like to get away from a short starter. I've tried different .010 patches including ticking and most of them burn through. I use either spit or bees wax-olive oil patch lube.Just got some Mutton Tallow from DGW so it might make some difference. Oh,the gun is a TVM Fowler .62 gauge.
