Cain's sells a "super rod" that you can get in all sizes. Some of the range rods out there, while excellent, are expensive. What I do is get a non breakable and then make sure it has female ends on both ends. Then I can put a T handle on one end. Also I likea range rod at least 4" longer then the longest rifle it will be used on. You can get super rods to fit the rifle with your choice of ends...

As for the maxiball mold, you can get them new through Lyman Molds. They are expensive, alsobecause the handles are not included, but are a good quality mold. Something else you might consider is trying some of the more cost effective conicals out there on the market. BullShop Conicals sells nice conical. Sabotloader seems to have good luck with them.
