I have a mold that has a GC and PB cavity. Was thinking of ordering a 4 cavity or 2 cavity GC mold and having the GC removed from half of the cavities by hollowpointmold. The idea is for much of the time I don't need a gas check but for some occasions it is desired. So I have these questions.
How well does a 4 cavity (or 2 cavity) mold cast if one is only pouring in half the cavities?
Does casting with only half the cavities work better with 2 or 4 cavities? Or does it make no difference?
Might a 4 cavity that has a single cavity for when I want a gas check be a good option. Is single cavity out of 4 being poured a better approach than say 2 of 4.
Can you provide some feedback on the work done by Eric at hollow point mold? That is where I was planning to send the mold to have the GC removed from some cavities.
I figure I'm probably going to make a several hundred of both styles initially by casting in all cavities to build up a stock of them and then only want to cast in the cavities that replace the base style I have used. Just don't know how well casting with half a mold will work. Or if there is a technique that makes it practical.
I am inclined to get a 2 cavity and convert one cavity. If that will cast ok or better than a 4 cavity then I figure a couple of hundred from a single cavity once in awhile isn't too much work and don't figure to burn through more than that over a couple of shooting sessions with a revolver. If 4 cavity will work better for using part of the mold then what the heck I'll get them done faster and have to spend more on the whole thing. But better and more money do tend to find each other all to often.
