Odd little mould , seeking knowledge and history

[RBHarter]

280473 Lyman .

There's little to nothing in a net search for this curious cat . It's 27 cal and 122 gr and has a realllllllly long gas check shank or maybe it's a rebated boattail ..... In any case it's over 1/8 of the bullets length and will take an hold a copper Hornady check.
Pictured with an NOE 279-124 and w/o check .

Do you have any of the older Lyman cast bullet books? Might be some anecdotal info in one of them.

 

[RBHarter]

I have a number 8 or 9 Lyman load manual but it's been AWOL since the separation move about 5 yr ago .

It's funny how there are volumes about some bullets like the Squibb design that is in my #45 Cramer but zip for a bullet so unusual . I guess if I run across a 1,2 or 3 CBHB I should pounce on them .

 

[Ian]

I'll look through my library next chance I get and see if it comes up. The only think I can figure it might have been designed for is the Mauser.

 

[RBHarter]

Another suggested it was a sister to the 311416 . Not much about that one although the search did send me here , Ben has one he plain based .

270 cal just isn't a popular dia .

 

[Ian]

Sorry, behind on coffee and sleep today, I meant SAVAGE, not Mauser. Seems that someone playing with the old 270/3000 Savage would have wanted to shoot cast bullets in it so Lyman made a run of moulds.

Sorta looks like a 311413, but with not so sharp a point!
Cant find anything in 27 though that looks close to it.

See if you can locate an Ideal manual #39. It looks like it debuted in 1953 and was produced up to around 1990 or so. Loading data does show up in my Lyman CBH, 3rd edition. I haven't found a story line on it yet though.

 

[fiver]

it has a scraper on the front and a lot of lube capacity.
I remember Mann/pope shooting a 28 cal rifle that would take a design like this.
he favored bore diameter dead soft lead bullets that were seated in the rifling.
they used them for chuck shooting.

 

[Ian]

Ideal #34 is too old to list the bullet and the cast bullet handbook #2 as well as #45 reloading manual lists the 280473 for .270 Winchester and Weatherby magnum. Not any significant history there. They were specifically listed in the load data as being gas checked.

280473 is mentioned in one of my Lyman books. I'll try to attach a .pdf of the page.

 

[RBHarter]

I knew someone would have a good answer !
Thanks to all .

This artical brings a bit of light to the bullet design .

This may be a heeled design for a very very different intent than suspected .

What's that line if it's stupid and it works it's not stupid ? This may well be a brilliant design , for a an obsolete design that is the origin of every barrel made since The Great War .........
Ok I'm sure that is a huge exaggeration . A rifle groove/land at 2/1 and only .004 deep could have just been a natural progression in to smokeless powder .
