	I fixed one one time finely opening a few of the lines on one side to let the air out. That mold was the only one I ever saw bubble come up through the sprue!

	Do you preheat it? Lot of brass in those blocks. Washed it with a toothbrush and soapy water Did you boil it for about 15 minutes?

	My NOE mold seems to work better if I pour, rather than have the ladle in contact with the sprue plate. Chuck

	Saw something funny elsewhere- a fellow said it was so hot where he lives that he put ice cubes into his casting pot to keep tin from burning off.

	I use a hand held propane torch to burn out the impurities in the cavity after cutting a new brass mould. More times than not you can watch it sweat out of the blocks and when it is all burned off you should be good to go. As I believe Joe said I have found that one is better off by not having any vent lines across the face of the blocks. I just stone a very slight bevel across the top off the blocks to let the air bleed out and to fill out the bases and I ladle pour. I learned this method to clean out the cavities from Barry Darr and it might be worth trying. I dry cut my moulds so there is need of prior cleaning but it's untypical of newly purchased moulds that should be cleaned first and then you can burn out the remaining impurities. JLouis

	John, You stone a vent bevel at the top of the block faces?

	BobZ yes I do and I will see if I can get a good picture of it later on. What I end up with is a slight V shaped trough going across the top of the mould. It's just deep enough to let the air freely vent out both sides of the base yet not deep enough for the lead to flow back into leaving a wisker coming off each side of the base. It's something I do to all of my moulds as it also provides a very flat and sharp edged base and not rounded. JLouis

	OK, I'll be watching I have never had any problems with the vents if I am casting at reasonable temps. Too hot and too fast = whiskers

	I have one in .25. It casts just fine, but it does hang up a little dropping the bullets. I need to stone the bur a bit. I cast everything at know temperatures. Molds between 400 and about 430 for most.

	Here you go BobZ pay no attention to the bullet, the punch mark was being used to center the cut off hole in the sprue plate. With the Brass blocks my alloy temp. is higher and between 800 - 820 depending on alloy being used. (You need to *Login* or *Register* to view media files and links) JLouis

	Hopefully the little shiny spot across the block shows how slight the 45 degree angle was stoned in. (You need to *Login* or *Register* to view media files and links) JLouis

That is the mold temp. westerner wrote on Jul 18^th, 2018 at 6:42pm: Soon as that thermometer gets here I'm going to try that. Lead melts at 621F, correct? Tin at 449F, correct? Celsius? 752F to 806F? I cast between 700-800 for most molds. Why do our molds not cast good bullets? Joe. I found my Lyman thermometer is running 40° lower than actual temp. I have been casting over 800 when I though it was 780°.

	I see your vent John. That is what I thought you were describing. Joe, That looks like a contamination issue or the mold is too cold. With that little burr on the nose, I would lean towards some kind of contamination assuming the mold is mating properly.

	I realized the thermocouple probe for my Fluke is only rated for 500° F. It wasn't giving me a good reading in the lead pot to check my Lyman The rest of it is all good for 1000° F
