Mold terms?

[turmech]

Would someone be will to give me a little education on some of the terms used by our custom mold makers?

Like RG4,RG2, Cramer style, and hollow point of one or more cavities.

I get that they are pins for the hollow point but what are the differences. I am thinking has to do with reversing them for hollow points/solid in the same mold. I think RG4 and RG2 only mean 2 or 4 cavity. Why do some order with extra pins?

Sorry if this is covered somewhere and I missed it.

RG4 and RG2 is the style of hollow point pins that NOE uses The pins are held by a bracket at the bottom of the mold and pivot away from the mold blocks when opened allowing the bullet to fall off. The number after RG does indicate the number of cavities the mold has.

Cramer style molds have pins that are held by a set of cross-pins threaded through holes in one side of the mold. When the mold is opened, you push the pins in to slide the bullets away from the cavity so that they can fall off the pins.

Most molds come with different pin options where you can cast different types of hollow points or a solid bullet with the same mold, depending on your needs/desires, all by swapping the pins around.

Hope this helps.

Some order with different pins because they are different pins. Usually small or large, penta, blank(you shape them) or plug. The plug pins with a Cramer mold means there is nothing sticking out the side so you can lay the mold flat. I don't know why anyone cares about that to begin with. I never lay a mold on it's side.

And hollow point of one or more cavities is self explanatory. If you don't get the option it casts solids.

RG comes from Rube Goldberg.

I think we need one of the village elders to launch a sticky for some of these terms.

I, for one, am wondering what "WFN" stands for.

"WFN" = Wide Flat Nose

What is a penta pin?

[dragon813gt]

Penta pin is a 5 sided pin, like a pentagon. Best pic I have of mine from a MP Mold.

Dragon813gt,

Thank you for clearing that up. I figured penta meant 5 but not a 5 sided hollowpoint.

The special pins on the Mihec/Cramer moulds are so the pins don't stick out the bottom, NOT the side, so that they don't interfere with a mould guide.

[dragon813gt]

Is a mold bottom really considered the part where the pins come out? Common sense tells me that they come out the side. In this pic the part w/ no pins is laying on it's side.

I can't be the only one that thinks this way?

on that style [cramer style] those pins go in and out from the side.
on traditional types [lyman and lee single cavity's] the pin goes in and out the bottom.

If you flip a round or penta pin upside down, you can cast a solid. But the portion that makes the HP cavity will stick out the bottom to the mold.

I get pins for solid points so I can rest the mold bottom on a hotplate for pre-heating when casting solids.

[dragon813gt]

I see now. I guess I've never had an issue because I preheat with it laying on the sprue plate.

so is it the Cramer style is reversable and can cast hollow point one way, reverse the pins and cast solid? extra pins for solid only allow the hollow point to not be damaged when reversed ? I get sometimes extra pins are for different hollow points.

Can the RG2/4 type cast solid? I am guessing there advantage is they swing out and allow the bullets to fall form the mold easier?

[tonyjones]

NOE sells RG 2/4 moulds with flat pins (for solid nose bullets) and HP pins. You may also purchase blank pins to make pins for custom HP cavities.

A Boolitpedia. That would be quite the undertaking.

Here are a few links to explain the RG's

I think I got it, thanks to the pics in the links.

One last question, if I may. When the hollow point pins are in place on the RG molds do they side sideways when the mold is open to allow the bullet to fall from the mold?

[captaint]

Yes, pretty much just that. Mike

Yes. They slide in the slot of the HP pin guide. They are very loose in the guide with plenty of wiggle room.
