A lee six cavity with small 358 boolit cavities, will need a lot of pre-heating to get well filled out boolits. Just dipping the corner of the mold in the alloy is NOT enough. Pre-heating on a hot plate for 20 minutes @ 400 degrees, is barely enough. One way to tell if it's hot enough is if all 6 sprues cut easily when the cam handle is swung to the right.

Cleaning is another thing done wrong many times, not clean enough is the problem. My method is to dunk the entire mold under boiling, very soapy, water. Boil it for at LEAST ten minutes, fish it out with tongs and hold under very hot tap water to rinse. The cutting coolant used while the cavities were being machined is very difficult to remove. heat and strong soap is what it takes. BTW Lee molds are not cherry cut, they're bored in a lathe.
