Help ordering a Mold

[joecool911]

I have a cad drawing of a bullet I would like to have made, but do not have the experience to do the online order from Mountain Molds. Can someone help?

My understanding is that he will only take orders for boolit molds drawn with his on-line software. You can order a mold through his website. Maybe you can get the software to duplicate your design. I've had some trouble understanding the dimensioning in it.

Good luck.

That is where I am at. Need someone here who has experience and would be willing to help.

I believe either Old West or NEI will cut your mold but you will have a set up fee to pay. That's the way group buys work, either we get enough for the fee to be waived or we have enough to split the fee and it's worth it to us. I'd PM 45 2.1 and see if he would post it if I e-mailed the drawing to him. You may get enough interest for a group buy.

If you could post a clear pic of the drawing with dimensions, I'm sure someone could translate it over to the MM site. I have only ever ordered 2 from MM, both kinda "on the fly" designs. [smilie=1:

I have a bit of experience working with bullet dimension values and nomenclature. If you could post an image of your CAD drawing, along with the dimensions, I'll see if I can convert the values to Mountain Mold's data entry page and then post a screen snapshot of those entries so that you can duplicate the order on your computer.

I am working on the Gates 431265 that was posted here a couple years ago. My computer does not show the images for some reason. But James Gates sent me the drawing to my e mail. If you gave me your e mail, I could mail you the file. Or if your computer shows the images, the image is here on this site somewhere.

Thank you!!!

I am working on the XXXXX 431265 that was posted here a couple years ago. My computer does not show the images for some reason. But XXXXXXX sent me the drawing to my e mail. If you gave me your e mail, I could mail you the file. Or if your computer shows the images, the image is here on this site somewhere.

Thank you!!!

jocool,

I located the CAD drawing in the forum files and scaled it out then entered the values into the Precision Cast Bullet Design & Evaluation software that I am developing to gain perspective of the design.

The values entered into Mountain Molds fantastic on-line design page are as close as the program tolerances will allow.

I have attached a sketch of my interpretation of the Mountain Molds values that will be incorporated into the mold.

It appears that Mountain Molds can produce a very close copy of the design.

All should be self evident but should you have any questions or comments, or think any changes need to be made, fire away.

Very Impressive Tom!

So when your software does come up for sale, will all these designs you have done be in the database accompanying it? If so, that will be fantastic.

[joecool911]

Wow, what can I say? Wow!

Tom,

I really appreciate your efforts. Your software is great! Have you discussed its use already? Is it mostly to help inturpret bullet design potential? I like the fact that a BC is estimated too!

It looks like the main differences are that the groves are more angled than the original and the nose has a slightly different angle. As I understand, the bullet was designed for feeding in the marlin 1894 lever gun. I see no reason why the suttle differences should effect that. From guys who have shot the bullet...they claim it is the best 1894 bullet out there. Feeds great and very accurate. Large meplat means it will be a great hunting bullet too.

Just to clerify...you have an arrow pointing to the 2nd buy button. I assume that this button will fire off the correct design?

James was good enough to provide us the design. All he asks is that he is given credit for it. "Gates 431265."

Do you feel the differences from the original are enough to make any kind of measurable difference?

Angled grooves does make for better casting - easier release from the mold.

[Dixie Slugs]

Looks like the hard work has been done indeed! This bullet was designed to give perfect feeding in the Marlin 94's. The weight can be changed by changing the design from the crimp groove back....but do not change the part from the crimp groove forward. The 265 gr weight is about perfect for the 44 Mag. Our load is 24/24.5 grs of WW 296 with a WW primer.
We hve killed quite a few hogs and deer with this bullet in the 94P's.
I will have other bullet specs to put on Cast Boolits that have proven themselves.

The software is being developed to design and evaluate cast bullets that will fit a certain neck length, throat-leade configuration and groove twist rate combinations.

Keep in mind that estimating BCs for cast bullets is more of a comparison process than a precise calculation. The BC is affected by bullet deformation and influenced to a large degree by bullet stability or the lack thereof.

A 55 degree (70 deg included) angle is the largest that the Mountain Mold software is set up for.

The Front Band Length values are graduated in 0.100" increments to the angle formed by the nose is somewhat restricted by the Band/Nose Length ratio. And the meplate diameter is determined by a percentage of the bullet diameter so the value cannot be precisely determined.

I believe that, since the nose length has not been altered, there should be no adverse effects to this excellent design.

The arrow is pointing to the drawing that incorporates one grease groove. The one above draws a bullet with no grease grooves and the one below draws a bullet with two grease grooves so after you have selected the type of mold material and cavities then click the buy button that determines the band configuration of the bullet and continue with the process of ordering and purchase of the mold.

Happy7,

Yes, there is too much research involved in each design to allow then to just evaporate into cyberspace.

At present, there are between 350 and 400 valid bullet designs in the database.
I am in the process of creating a module that will allow one to archive inactive designs and recall them as needed. Boy did that turn into more than I expected.

After a closer examination of the changes made to the Gates 431265, I would rather you did not use my name on the new design.
The reason is not that I think your design isn't good, but rather there are cherries out there cut against my specs. I do not want to have to discuss in the future just what was the original design and what is a copy.
Thank You.....James

James,

I fully understand. The changes have been made to the posting and the images.

Respectfully submitted,

Your design looks good and should feed well. The angle of the lifter in the Marlin 94 is at a rather steep angle. The trucated part of the nose must go inside the chamber while feeding and not hit on the upper part. There are some great designs out there that are excellent game bullets that do hit the upper back of the chamber/barrel....that's all.
Some folks on the forum ask me to also post the Extreme Meplat designs. I did, but seems to have stirred up some people when I asked to change the name if they modified the specs. I really do not care if they modify the designs, but there are cherries out there at present with the original specs and I do not want to get into who did what. I recieved some rather caustic remarks and realize now I should have never posted the specs. You are quite welcome to any on the designs we worked up, including the 12 bore solids.
Regards, James

If I order the mold above from Mountain Molds, will it size properly without ordering over-sized? Would I order a .431 sizing/lubing die?

[Dixie Slugs]

As I see on the MM spec sheet, he has set WW as the alloy so you should be fine. Most Marlins are most accurate with a bullet sized .431"/.432" A .432" sizing die will just bunish the bullet and add lube. Either a .431" or .431" die would be fine. That same bullet cast with linotype would fall about .432"...still fine! Even though he set the alloy at WW, we do add a little tin to help fill out the mold...but that's just what we do and others may advise you different. We also use Hornady gas checks and size our bullets base first in a Star.....but also have use a 450 sizer.
Just some thoughts...that I am sure some may disagree with. Note this as I am going to request that all my posts and threads be removed
