Hoch mould (Read 22736 times)

	I am having trouble with my 38 cal. Mould. It is a 375 grain Hoch every thing fills out fine but the base,it won't fill out. After casting and opening the sprue plate I turn it over to check the base and some where the base doesn't fill out . Not in the same place every time I have tried different alloys. I'm bald so I don't have any hair to pull out. Any help would be appreciated . Thanks Bill

	I have had several molds that would not fill out the base consistently. All base pour. I would take a fine Norton 2 x 8 inch stone and lightly run it across the top edge of both sides of the mould blocks (which in my case is the base of the bullet) at a 45 degree angle and make a very small vent line. That usually cured the problem.

	Have several Hoch moulds, have had the same problem. In my case I have had to cast at a higher temp and faster than my base pour moulds. It was the cure for me, wish you luck in your quest.

	I have tried casting at higher temps and can get a few good bullets that way.verging on frosted is the only way I can use it. Bill

	Have found my nose pour Hoch 38cal 315gr mould to be the best casting mould in my inventory. Am guessing that you are not getting the entire mould (especially the bottom sprue plate) hot enough and casting too slowly, which lets things cool between bullets. Mine works well when casting temp is 755-775F and cast at 75-100 bullets/hr. If I cast at the slower rate of 50-60/hr like with the larger/heavier PJ/Saeco/BAC0 moulds, it does not cast as well. Wish all my moulds cast as fast as the Hoch.

	I am with SSShooter on this. I also have a .38 hoch mold, 38-300 I think is the number. I have to cast it hotter and faster. What I have done, and please don't flame me for this, is to take a propane torch and apply some extra heat to the bottom plate to get it it up to temp. Once I have the bottom plate hot enough, a good pace will keep things even and it casts like a dream. I also have a 45 cal 350 gr mold and it has been a pain to get good bullets out of but once I used this method and got the alloy temp up a little more it casts nice bullets. It may take a little playing around to find the right alloy temp as a little too high and the bullets will frost and may be a bit rounded on the edges of the driving bands, but once you find the magic number, Hoch molds are just a joy to cast with. YMMV Sam

	In general nose pour molds want to be run hotter and faster. On my Hoch molds I cast at about 800 to 825. The other thing that you can do is open up your dipper just a little. Find out how big a hole you have in your dipper and open it up a few thousandths the increased pressure will help fill out the bases. 40 Rod

	I found the same when I started using Hoch moulds. Hot and fast is definitely the answer. They behave quite differently than all of my other moulds. 40 Rod, I haven't tried opening up my ladles. What type of ladle are you using? Thanks Chris.

	Your sprue plate could also need adjusting of which is not uncommon and that will also create the issues that you are having. JLouis

	For perfect base diameters and completely filled out bullets: heat the pot & mold up to temperature so after a 5 second pour with the ladle spout in the sprue hole ... the sprue puddle frosts in 5 - 8 seconds depending on bullet weight Using this method - one can even cast without using a thermometer. If the sprue is cut before the puddle frosts ... you'll have slurried lead on the bottom of the plate and top of the mold

	What's your alloy's temp? Turn the heat up 30-40* Are you preheat'n the mold? How do you clean the mould before use? LG

	Clean the mould before use? Shouldn't need cleaning, at least I have never found a need for it as it clean when I finish so its clean when I start. JLouis

	Oil the moulds when done- Flush the mould with brake cleaner before each cast'n session. LG
