I need a new Postell mold

[Kurt]

Kurt,
YOu mention George Russell as designing the "Postell" .
So how is the connection that the bullet is called the "Postell"?
Did George design it FOR Postell?
Is this similar to the 40 cal bullet 410663- commonly called the "Snover"
for Ron Snover, but actually designed by Richard Gunn?
beltfed/arn ie

Arnie I ran across that name when I was looking through a old Ideal Catalog while looking for a bullet for my .44-75 Ballard. They had the .457-132 postell mould and it gave Russell's name as it was made for him. I don't remember all the details if Russell designed it.

This explains the naming:
George Russell is said to have designed the bullet for the Georgia Volunteers team,
under Capt Postell. And obviously, the latter name stuck

Similar to the Snover bullet designed for him by Richard Gunn

All of this talk of duplicating the original Ideal 132 with a beveled base you have to ask your self....why didn't Lyman carry it through as the original or even Walt at NEI ?? I personally have never found a beveled based bullet that shot worth a hoot compared to the flat based or even cup based for that matter.

I’ve sure enjoyed this thread. Had no idea that these were so hard to come by and am all the more grateful for the help here, especially the bullets sent! And especially Kurt turning me on to other flat nose Lyman.

Guess I have slim-to-none chance of finding an original 457132 in 475gr. Had hopes of seeing just how close I’d got with my scaling-down efforts via a comparison to the original. I did manage to retain 95% of the Form Factor and BC.

I’ll have both molds soon (still undecided on which weight for the 132) but they’ll both be plain base.

For anyone interested here is a rendition of the original. A very considerate member here sent me a bullet cast from an original Ideal 457132. Using calibers I did my best to recreate in TNT software. The weight is within .0003gr (actual bullet weight to diagram projected weight) so I think results were acceptable. The areas in some question are the lube groove angles, the bevel base angle and the radius. Radius is returned by the software and I have no way to validate but I think they are quite close.


Many thanks to Old-Win!

Well the previous was an errant post while trying to post a picture of the actual post. Been away from my desktop where I had access for a couple days. Here is the bullet my drawing was made from. It is on the left.

What's the mould number on the PJ bullet?
It sure isn't his Postel......

[SgtDog0311]

Sure isn't. Should have taken a picture of just the one bullet so as not to confuse the issue. Just ignore the one on the right.

Been looking over this since I got back, and looking at the mold on ASSRA as well as reviewing something desert deuce said about the nose, recognizing of course that my purposes are different than his.

I've said all along I was not sure about the radius which is returned by the software rather that being assigned by myself. That radius line forms the line from the nose section represented by the round circle on my drawing and the tapered line in front of the front driving band. I've found that if I use "Elliptical" in the "Nose Type" of the data entry that I can make that resemble the nose of the ASSRA mold better, at least to my eye. However, I am not so sure if it resembles the bullet I have in hand better or not. Have a look and see if you agree. The diagram does not even show a radius once you opt for the elliptical nose type. I'll post it in below.

Don't pay any attention to the BC in the previous... tried to edit and replace with this one but no-dice.

Wonder if a custom mould cutter like Steve Brooks, would be will'n to cut a mould to those specs?

There are some other obvious differences (like the shape and width of lube grooves) but the nose shape seems a closer resemblance to bent ramrods mold.

I'd mentioned previously "not knowing the angle of the lube grooves" before on my drawing efforts but these look 'narrower' as well in relation to the bands. May give some credence to the contention that not all 457132s were the same. Then again this is a Lyman mould block and we have no measurements at all as yet.

[desert deuce]

Agreed SgtDog, hope to have more photographs and maybe better description and maybe a measurement or two next week. I shoot with Bent Ramrod couple times a month and he lives close by. I think we are on our way to finding out more than we knew a week ago. Stay tuned.

I have had at one time 5 different Lyman 429421 moulds and one 431421, none of them were the same visually, only similar.

The three IDEAL 429421 moulds I have are pretty much dead nuts the same visually.

So, I am really encouraged to see a bullet closer to the original design in a LYMAN Mould Block than an IDEAL Block.

Gary, I have some of Steve's and I like them. I like BACO and Saeco blocks as well. I want to stay south of 500gr. I was looking at the Saeco 645 for a starting point but like what is said here about the original Ideal. I was thinking to lift a drawing for the original and then scale it back to the 475gr and go from there. Wish they had more dimensions or someone had them for the 475gr. Couldn't find one anywhere other than KWs lead. That will have to do unless someone has an original and wants to share measurements. Maybe Frank over on ASSRA has a drawing.

For the original original, the mold would have to be a one piece block and handle. Mine is the newer kind using attachable handles.
