During my sorting through the shop I came across a good quantity of sealed H870 jugs. I have used it in the past in some of my loadings but am just curious if anyone still uses the stuff. I will likely try some new loads for the 300 Magnums and see what the chronograph says. Thinking about 200 grain bullets. | ||

WOW, what a find. Since it was discontinued more than 10 years ago, it is not easy to find, if at all. I would like to see how it does in my 264WM, but all there is left is the mil surplus equivalents.

Yes, I have some from a bygone era; as I recall it has the burning rate of powderd charcoal briquettes. | |||

I still have some and use it in my 30/378 and 300 RUM. It's a great powder with heavy bullets in large overbore cases. Best I have ever used in my 30/378 with 200+ gr bullets. "300 Win mag loaded with a 250 gr Barnes made a good deer load". Elmer Keith | |||

H870 is very similar in burning speed to the old H5010. I'm not sure that this is of any help to you since 5010 data is somewhat uncommon. But if you have a chronograph and a good sense of how to judge pressures, some excellent loads can be worked up with H870 in large (for bore) capacity cases. H870, like most of the spherical powders of the era, has a reputation for leaving a stubborn residue in bores. | |||

I have used it before and have several of the old Hodgdon load manuals, so I am setup to use H870. Plus a Oehler M 43 system. Speaking of 5010 I also have a sealed 8 pounder. How do you tell when a reloader is an old guy? He has powders no longer manufactured! | |||

I love it in a 7 Mag. Down to about 3 pounds from my stockpile. Got some W872 to try when its gone. The W872 is great in my 300 Wby. | |||

Here's a chart for mil-surplus powder in other calibers. Haven't tested any of these loads but it's a good reference. https://www.scribd.com/documen...&source=impactradius | |||
