If you can talk at least 9 others into a potential RG version of the .600 meplat.
Then attached is a draft for an HP design that potentially reduces the pure PB weight to ~ 567 Gr.
If cast in WW alloy that cast weight will be ~ 550 Gr…
As I have said previously… it is not the way that I would choose to go… ballistically…
However I am at this point only trying to help…
The full package with a couple of large insert pin designs along with a flat pin may be the salable point here…Take Care, & Stay Safe…

Blammer – this thread should be in the Group buy discussion. Since you started it, there should be a button for you to move it. Then once you have ten buyers there, cornmastah or one of the other guys will start an active group buy thread.
In any case, I’m in for a four cav. Or five if they can fit that many into one block.The total number of cavities will basically need to depend on the maximum length of the mould that NOE wishes to manufacture, & the CNC required spacing between the cavities… to prevent the mould from overheating.
To illustrate what I am saying attached is a theoretical mould model.
It may be that with a .730 dia vs the original .680 Sabot that the longest mold body will only yield 3 cavities if one spaces them as shown in the attachment… while the .680 was able to basically yield 4 cavities.
My longest NOE 5 cavity is I believe just over 4.1 inches long.
I could find no record in the NOE mould design history for a .730 dia mould design… in the historical records that are available to the forum membership.
Thus it would be undiscovered country mould design wise…
That would most probably mean that the new slug mould design would be a 2 to a 3 cavity mould… at best … sans any RG mould pin design thoughts… which would basically mean that everything is flipped 180 degrees placing the .730 dia slug base just under the sprue plate… instead of the nose dia @.600…
If the final slug design stays as last drawn up on 3-6-2021.
Take Care & Stay Safe…
I sincerely wish you luck…After I posted the mould length thoughts earlier I realized that if the mould is made the way that it was originally drawn up that the .730 dia would break through the standard NOE mould block where the mould handles cutouts are…
Thus if this design as it stands right now gets at least 10 individuals to say that they want to purchase one then the design has to be cut with the .600 nose down instead of up.
At least that way there will still be enough mould block to not have the mould cavities break through the sides of the mould where the mould handles attach… though the wall between the mould handles and the inside cavity diameter will still be rather thin…
It is either that or there will be a need to make the mould blocks wider than the standard NOE mould blocks are to allow a .730 dia mould casting to be cut into the mould block…
That is most probably a good idea anyway…
Just thought that I needed to say something which ever full bore slug mould design is finally selected…
It may also be why the original mould designs stopped circa .680…
It is what it is…

I HAD a NEI 12bore bullet mould that dropped a .735″”, 2 band slug. I pan lubed them and cut them out of the lube with a 12ga hull with the folds trimmed off. That diameter was no problem for my rifled 870, and they grouped well, but stout loads of Blue Dot at that 600gr+ bullet were just more fun than my system wanted to deal with.
I also have a number of NEI bullet moulds.
That mould manufacturer used a bigger mould block, & thus was more easily able to accommodate the larger 12 GA full bore diameter… Thus my point on the need for a bigger mould block if that full bore design was to come to some kind of fruition…
Unfortunately the owner operator of NEI died a number of years ago, & it is my current understanding that NEI is no longer in business… as the only offerings that one can apparently locate are on EBAY…
According to the postings on the forum and on the NOE store if for a new buy one apparently needs at least 10 committed buyers for a new bullet run as noted by the recent email nudge in regard to the current single potential open run for a 412-218 RF has been in stasis since before COVID… reared its ugly head… in 2019… That mould is still several short of the 10 needed… as noted by the latest nudge to try to find a couple of more individuals willing to commit… and is still in stasis…
In December the 350 Legend design… 357-190-RF had I believe 17 preorders, & yet when Al opened up that mould for prepayments in early January of the following year in preparing for the afore mentioned mould run… only two of the aforementioned number actually signed up and paid the money up front… At the end of January those funds were refunded and the order was closed down as being unsuccessful. I know as I was one of the two who committed and had my money refunded in early February… Thus one ends up with the tire kicker posting by AL on
Group Buy Rules
HOW WE RUN OUR BUYS
Group Buys generally start in the “Group Buy Discussion” section of the forums.
New buys are posted to see what level of interest is present and to get an idea in
numbers of moulds wanted. This is also the time that any design changes are
be discussed and made.Buys with sufficient interest are then moved to the Active Group Buy Section of the forum
and the buys are added to the site in the group-buy category. The Order page on the site will
show the details about the buy including start and close dates, minimum orders required,
and the finalized drawings for the mould.When you place an order, you will be billed for that mould. Due to the large number
of drop-outs from previous buys, we are changing this to determine committed buyers
and remove the tire-kickers from the equation. At the close date, we will either
announce the close of the buy and the expected run date and shipping date, or we will
announce the failure of the buy to generate the minimum number of orders and refunds
will be issued to those in the buy. All refunds should be dispersed within 10 business
days after the close of an unsuccessful buy. At the time the buy closes, the forum will
also be updated and the thread moved to “Closed Group Buys”.For successful buys, Tooling generally takes a week to 10 days to prepare and then moulds
can be cut and prepared for delivery. Expect production times of 5 to 6 weeks from close
of buy to ship date.I give full credit to Al that later in June of that same year there was a quiet run of those exact same 350 Legend design moulds made, put on the store website.. I bought two different versions at that time… and I believe Alvin York bought one too just shy of fathers day…
At that time I also posted that there were now 350 Legend … 357-190 moulds available…
Still it took almost a year for that run to be completely sold out…For moulds that have been run before, & are completely out of stock in all mould versions… According to NOE one apparently needs at least 5 committed buyers for a new mould run… according to what I believe is still posted on the NOE forum pages…
HOW WE RUN OUR INVENTORY BUYS
Inventory Buys start in the “What you would like to see ran” section
Moulds that are listed in inventory but out of stock are posted to see what the interest
is and start to get a idea of what kind of orders can be expected.
We still reserve the right to run any inventory item at any time – and this does not make
the item eligible for any kind of a discount at this time.After a item has shown enough interest It is moved from the “What you would like to see ran”
section to the “Active Inventory Buy” section. This is were you place your order and can
check on the progress. When a buy gets 5 orders, it is scheduled to go to the shop.
At this time a last call is issued too. As soon as we can get it worked in to the schedule the buy is
ran and it is moved to the “Closed Inventory Buys” section. We try to do this in a timely manner.As soon as a run comes off the mill it is posted on our website and a PM is sent with
ordering instruction and a discount code. We offer a 15% discount on inventory runs through
our forum.If a run does not get 5 orders or it takes longer than 6 months to get 5 orders
it will be evaluated at that time and either will be closed or extended another 6 months.So call Al on the phone … & ask what is going on… to get moulds into stock once again…
COVID appears to be slowly winding down…Single mould requests are nice but that does not apparently meet the current NOE posted requirements as noted above to justify a new mould run… Unless one can talk Al into changing the new run policy… nor something that the forum administrators cab easily keep track of…
It would be nice to see the mould bins full at NOE when one goes to order something that is near and dear to ones heart… when all the other mould sources are out of stock or months out in delivery…
