I must have had a small piece of crud in the spout of my RCBS pro melt. I tried pressure casting a cycle and on the next pour I noticed I had a faster more powerful flow of lead coming from the spout. BINGO! Things got better instantly. Super sharp bases and complete fill out. Happy camper.

Waco,
Try using a 5/64" drill bit with a gloved hand in the nozzle of your pot to pull debris out of it. I'm not sure about the size on an RCBS but a 5/64" bit fits the Lee 4-20's just right. I do it just before I start casting and mid-pot. Surprising how much junk comes out when the bit fits correctly.

My last new NOE mold...last Sept...was a bear to get going. It took the better part of 1000 bullets for the bases to start filing out. But, just like a flipping a light switch...it started raining good bullets. I have not used it since then...hope it doesn't go through that again.

I had trouble with a new NOE .44 mold... bases weren't always filling out. I got impatient and broke the upper edges of the mold with a fine stone. Just a tad, can't even see it. Did the trick. Other thing was to just keep pouring some lead on the sprues, give the bullet time to draw alloy. I find it helps fillout in a touchy mold.

I have an ribs 200 gr 45 mold that did same thing. To get it to run righ I had to increase mold temp. And put more pressure on mold when pouring ie. bottom pour with higher alloy level initially

Lately I've been cleaning my moulds with real hot water. I just fill up the Mr. Coffee and use a dishwashing liquid with lemon in it. I heat cycle and clean it again.
One thing that works for me with RG series moulds and a hotplate, is to heat both top and bottom of the mould. I heat the bottom (Pin side) last and it really seems to make a difference how fast I start dropping good bullets. I also spin all my HP and DP pins in a hand drill, using fine steel wool to polish the pins.

I guess I've had better luck with my first .44 N.O.E. 4cav. I followed the instructions, couldn't get one decent bullet after 20 pours. Then I washed out the carbon from the smoking with Brake Cleaner. Next pour dropped 4 PERFECT bullets. Sometimes it pays to do it the way you learned 30+yrs ago.
