260-63-FN-AR4 4 Cavity GC

It might be interesting to see what can be done… if Al is now finally able to devote some time and labor to potentially new design versions…
I have had several HP versions custom made for the 25-20 for my own experimentation purposes.

An NOE version of said mould might tend to attract some interest… especially in an RG version.
An NOE drawing would need to be made up to illustrate the concept… using a RG pin design vs the original single cavity Lyman HP pin design…

If Al can now truly make RG pins in any diameter I would also sincerely interested in seeing the blank RG pins coming back into stock in a number of appropriate diameters for experimentation purposes down the line…

I might tend to recommend that the HP pin in what ever version is finally voted on … Have at least a 7 degree angle taper to augment the cast bullet dropping off the RG Pin… Too shallow & thus potentially deep a taper angle (below 7 Degrees) tends to make the cast bullet tend to want to stick on the pins.

Take Care, & Stay Safe…

The pins would have to have a specific length shoulder cut in order to work properly for each specific mould design… The traditional flat pin design for cartridges like the 25-20 will tend to be that length… if all three traditional mould pin offerings are to continue as standard… Flat Cup & HP version pins…

Your reply also tends to potentially indicate that there might be a potential for more of the basic .200 & .250 long blank pins… potentially available for experimentation…

Finding & cutting new HP pin designs will thus be a matter of the location of the first cut for the shoulder… prior to cutting something like a .105 dia RG pin into that needed shoulder.

The traditional Lyman design in the original offering utilized a straight .105 diameter pin by comparison… The potential advantage of that detachable Lyman pin design is that one can keep the mould closed and physically remove the pin prior to opening the mould to drop the cast product out.

While one is at it … the max pin diameter sans the shoulder dimension basically needs at least a minimum of .025 wall thickness to fill out properly with molten cast alloy… when designing one’s own pins… for an RG type captured pin design.

Any less than that wall thickness around the pin diameter & one starts to run into complete fill issues and more less than optimal cast product which ever fill method that one tends to prefer.

For air guns the basic alloy of choice is by definition pure lead… to define the cast bullet weight.

For the remainder of the spectrum like the 25-20 cartridge the normal alloy of choice that NOE uses to define the forecasted cast bullet weight is basically wheelweights… The actual alloy composition thus will change the final cast bullet weight…

If you look at the standard NOE RG HP pin designs and run the numbers on the cast bullet dimensional dwgs … you will see that this intel is also basically is built into the design software … However that same software also allows one to change that initial pre determined diameters & depth…  as one sees fit…

Take Care, & Stay Safe…

Sure would love at least a 2 cavity GC version.  doesn't have to have hollow point capacity
