One can turn the temp up until start casting frosty, then turn down a bit. Even frosty is not all that bad, still good bullets or balls, I have a couple moulds that I beagled and not venting the best, they require a high temp to cast good boolits, yep boolits, not bullets. :wink:
Too cold often make for wrinkled projectiles and incomplete filling of the mould.
