When I first started casting 22 cal, I couldn't keep the mold hot enough, so I used a hot plate to get it up to temp, then start casting, maybe 4 or 5 drops, then put it back on the hotplate to heat the mold back up. After I figured a few things out, like pouring larger sprue puddles, I no longer needed the Hot plate trick.
Good Luck.
