Probably good for heavy bullet 3006.

30 30 not so much.

I doubt it would work for blowing stumps, too slow of a powder. Check and confirm, it seems like it would be similar to H870 or aa8700 for speed and on the slow side for /06. I doubt you could fit enough in case, to get good loads, in an /06, even with heavy bullets.
I believe it's powder for 50BMG and would work in cases like the big "overbore" mags, 30/378 and the ultra mags.

I would be looking for trades or use it as excuse to get another rifle to use it in.

I would agree with Robert. I had to find data for my 6.5x06 when I got it. Then there was very little data other than Ackley. Tried his loads and had a case life of one shot. Primer pocket's expaanded so much the next pirmer could have dropped into place. It did eventually work out but I don't believe I would use any powder I had no data for. I had picked up a lot of powder called Super balistite for which there was no data. Sat on it a long time and finally found data in a very old Lyman manual and then no other mention of it. Worked very well. It must have been the origional Bullseye, same data but Bullseeye was a lot cleaner.

If it's the same burning rate as H 870 or T 870, it would work well with 300 Weatherby. The H was Hodgdon of course, and the T was from Thunderbird in Phoenix..  I also used the old 870 powders in my 8X68S..

Thanks all, I think I will have to look at purchasing another rifle, maybe I can find some data for 7mm Mag, always wanted a cheek buster! Or just go with a 300, I mostly hunt white tails here, so they are a little overboard, but hey at least I can reload and plink, That's always fun!!

IF it's the same as the old H870, Nosler #5 lists, 160gr over 75.5gr H870 to start (79.5gr max), Fed 215 primer and it shows this as the fastest load.
http://data.hodgdon.com/cartridge_load.asp
shows a load for US869 for 160PT of 77gr start, 80gr max. I believe US869 is H870 updated, cross checked and it's data closely matches H870 data.

I had thought about getting some of 870, when 8lb jugs were on sale, price was right, for use in my 257wby. I had researched powder and load data at the time. If this is the same powder, they had said use H870 & AA8700 data and workup from there.

I would of course use caution and follow all the usual safety guidelines. Remember you have no data for this, just what may be a similar powder, this is why I decided, price may not be such a good deal and passed.

 I use H870 exclusively with 7mm mag loads 160 grain or higher, but note loads for 270 Weatherby mag and 264 Winchester mag loads in my older Speer manual. Bought lots of H870 before the liberals took over.

Something I forgot to mention - I called Thunderbird in Phoenix for loading the 8X68S with their T870/220gr bullets
The answer was-Fill the case and squeeze a bullet in. Had to modify a bit. Finally settled on 82gr.
On the off chance that anyone out there has an 8X68S, I'd advise cutting back a few+ grains.
My rifle was a Sauer Lux, another ill advised sale. Beautiful rifle.

I use Olin 860 pull-down with the 50 BMG, bought 100 lbs back in the day. I think it is real close in burn rate to your 870. It is slow powder, not sure how well it work for your application...

WC870 Here is some of the exact original type powder as was sold by Hodgdon, called
H870, until discontinued. A ball powder originally used in the 20mm Vulcan
round, until replaced by WC872. This powder is also very similar to Accurate
Arms AA8700. Because of the lot to lot variations in burn rate, be sure to
begin with listed starting load data. Works great in the .50BMG and other
large capacity magnums.
This is pulldown ball powder.
$48/8# jug; $176/4-8# jugs ($44/jug); $240/6-8# jugs ($40/jug)  http://www.gibrass.com/gunpowder.html
