Old information?

[Potashminer]

Back in the day, Winchester used to publish a reloading "pamphlet" - 8 1/2" x 11" - perhaps only 4 or 5 pages? It had loading data for 458 Win Mag using the W-W 510 grain bullets - pretty certain it was with a ball powder and duplicated their factory load at the time.

I had the thing - put it away somewhere "special" and now can not find it!! I am wondering if anyone here has a copy of it. I am not interested in purchase or full copy - just a picture of the 458 Win Mag info with the 510 grain Soft Point, or whatever that load was in words, would be fine.

A hazy memory now, but quite sure it had no Start or Max load - just one line - to be used exactly as listed - brass, primer, powder, etc. and was supposed to be a duplicate of the factory load of that time.

Any help appreciated!!

(EDIT): just looked on-line Hodgdon's reloading - same thing - does have loads for 510 grain bullets - no Start load - just a Max load listed. But for 6 different powders - most of them are IMR powders. Sort goes contrary to all the reloading manuals talking to "work up" to a max load. I find that curious???

Good morning, I’ve got that pamphlet. It only list 748. 73 grains for 2040 and 75 for 2065. 39 and 41000 c.u.p.

Thank you, MTM! Any chance that they mention the primer they used?? Pretty certain it would have been the Winchester Large Rifle Magnum, but thought I should confirm that. The "modern" Hogdgon data uses CCI 250 primers. I did also find a Hogdgon 2011 "Annual" Reloading - like a magazine - same loads as is on their website - showing that 75 grain of 748 as the only W-W powder, only one powder weight for it is listed - all the rest are IMR powders - same deal - only one weight listed.

In the 'Winchester Ball Powder Reloading Data' booklet dated 1978, which also shows the loading info mentioned by MTM, they have a paragraph on the primers used in all their testing which states:-
"All primers used for testing of the data were standard Winchester-Western primers of the applicable size. We caution against the substitution of any component as it can alter the ballistic level of the load. The only magnum primers used in our data testing were for the .357 magnum and .44 magnum cartridges".

All good, thank-you - dated 1978 sounds about correct for the pamphlet that I so carefully stowed away!!! We are in our 4th house since those days - I have seen it every time we moved, so it is here somewhere!! Found a real good place for it this time!!!

Many of the old reloading manuals are available in PDF online.

Thank you - I followed that up and downloaded #14. Apparently, we differ what we mean by "old" - that #14 is dated from 1994 - I had about 19 years work in a mine by that year, so not really "that" old !!!

#14 also states at the very beginning of Metallic Cartridge section "All loads listed are maximum loads. You must start 10% below the suggested load and work up to the maximum load carefully"

If you want old I have a Speer loading manual from 1962 that was my grandfather's. I can look it up in that!

 

[Potashminer]

Ha! Now we are talking! But I do have Speer #2, dated 1956 and Speer #5, dated 1961, although printed in 1962. It was the Winchester published information I was after, and looks like I have it. But, thanks, anyway!!!

Thank-you, diopter - the era of that reference sounds like what I may have had on my mind?? I have some of those old 510 grain bullets - yellow box with red lettering, and apprently have some brass in the same style of box on the way, so was thinking to try the "old school" loading...
