Winchester 680

[hdwhit]

Got some of this Win.680, any idea what it's for and data. Can't find it on-line, it's old.

Yes, it is old.

I put 15 grains of it under a lot of 110 grain bullets in M1 Carbine cases.

It is used in a lot of small capacity cartridges. I have several manuals from the 1970's/1980's and if you PM me with the cartridges you're interested in reloading, I would be happy to look them up for you. Turnaround may take up to two days, so be patient with me.

I'm loading 22-250, with 52-55gr. bullet. I saw last night it's faster than 4064 which is what I load now. That's the only powder I have used for the last 40 yrs. I don't know how to PM, sorry.

Double post, not sure how it happened...

And it wasn't even in this thread...

Wow very cool, BUT what would you start at. 4064 is what I use and I'm loading at 33.1 gr. How much less or just try some thing? I've never experimented but it's worth trying.

Do NOT load 680 weight for weight with 4064, you'll have chunks of rifle sticking out of what remains of your face!

If I had a can of Win. 680 I probably would find a way to use it in something. I've used extrapolation in the past to work up loads with powders for which data wasn't available in a particular cartridge but then I've reloaded for a long time for a BUNCH of different cartridges and guns. I've never had a squib or damaged a gun but those are risks of going where no one has gone before and probably that journey should be reserved for the very experienced reloader.

My apologies, but Grumulkin is right. Unless you know a very experienced local handloader that can help you out, it would probably be best to forgo using your 680 for reduced .22-250 loads.

I misspoke when I said that:
"You could work up reduced loads for your .22-250 using W680 without too much trouble."

Like Grumulkin, I could do it, but I've been handloading a long time and have experience interpolating load data and working without published data.

This is absolutely not meant as an insult, but when you asked about substituting W680 grain for grain with your 4064 load, I realized that you probably don't have the background for a project like this.

I am sorry if you thought I said I would use the weight data from 4064. I know it doesn't translate. I know i would have to drop it down quite a bit due to 680 being a faster burning powder.

From the 1976 Winchester-Western gimme manual:

22/250

50 gr Spire Point 748 35.0 gr 3660 50K psi

50 gr Spire Point 760 39.5 gr 3700 49.2K psi

9mm - not listed for this powder.

Hey BrockLuno isn't 680 a faster burning powder than 4064. I 'm just looking at the faster powder statistic and wondering why I would load that much of 680. Maybe I am missing something.And should I start at that high a weight. A side note what do you see for 55 gr. Maybe that's the thing I'm missing. I'm thinking of the round being loaded with the bullet being 55 gr.

John, you may be better off trading off that 680 for a comparable amount of a powder you use. Where about are you located, I have been wanting to try that powder in my 218 Bee and 30 Herrett. Both are suitable and supposedly do well with it. There are plenty of better choices for your 22/250. 680 is a pistol powder and much faster than anything I have found published for that caliber,and I would be hesitant about experimenting with that application.

As far as I see in my research ,win. 680 is for rifle loads, i.e. 218 bee, 30 Herrett. But being that as it may be if you want it , it's yours.I live in Brookline Mo. just outside Springfield.
