I'ld give them a good sniff, just to make sure their allright. Most likely they are, but I know I had some old H322 that went bad, and it ended up as grass fertelizer. You might get some info on those powders if you e-mail the company's. gypsyman

For the H570, I found this piece of info - take it for what it is, a random sighting on the net:

You can not get it any more as they quite making in 1965-66 I think. I got mine from a man that had bought by the case. H570 is the slowest or was the slowest burning powder ever made. They used it in the .50BMG loads. H870 replaced the 570 as the slowest burning powder and in the .50BMG.

It is listed on this burn rate chart - not the slowest, but pretty close:  http://home.hiwaay.net/~stargate/powder/powder.htm

Google gives some other results (http://www.google.com/search?hl=en&rlz=1B2GGGL_enUS203US203&q=h570+powder&start=10&sa=N), and it looks like the .264 Winchester Magnum shows up a lot in those results.

Sounds like you picked up some fertilizer to me.

Me too. Most of the old powder were in either tin or cardboard with tin ends. I had old powder that was sealed good and stored in a cool place. I still got rust in the inside of the can. The powder was good, but brown from the rust. It got dumped in the yard.

I totaly agree , not worth the chance at that price .

P 5066 is a pistol powder. The Lyman Reloading Hand Book 41st ed. has load data.  I used it back in the early 1970's.  It was a good powder.

I used to use old shotgun and pistol powders in small amounts to fire form 280 brass to Ackley Improved.  I plugged the brass with tight wads of toilet paper and fired it in my workshop.  Never worked as well as fire forming with a bullet.  In the total scope of things like this, it is hardly worth it to skimp - especially on hunting ammo.  Ten fingers are nice to have and two eyes work better than one.  Stick with known loads of premium powders, and current data.

Now that you have bought them, I recommend disposal in the yard.

I used H-570 in the .264 Win Mag. This stuff is as big around as the lead in a pencil. Burning rate is similar to H-870 but way more bulk. If it smells ok and you have an overbore case give it a try.  You won't be able to stuff enough in the case without compressing the powder to give you any trouble.

I know zero about thoes powders other then looking them up in a old Lyman book, but I will say this back in the late 60's I bought 100lbs of surplus WWII H-4831 and i'm still shooting it only have 3-4lbs left and it's still smells good.

If your not sure don't use it.
