I had a couple of loads for my guns built around the H870 powder. Unfortunately Hodgdon is doing away with 870. Is there a big difference in burning rate between these two? Has anyone worked with both that can shed some light? Thanx

Hi POP -

I've used both in my 7RMag with 160's/175's, and, the lot of Accurate 8700 was about 2 grains slower than that lot of H870. Wasn't near as dirty, either.

R-WEST

Faster to slower:

125. IMR-7828
126. AA-8700
127. N-170
128. H-1000
129. H-870
130. 24N-41

Thanx Steve. It does act differently pending on caliber though. I did notice that!

for what its worth I like H1000 in that burn rate area. All I use in 7MM Remington Mag.
72.5 grs
150 Nosler BT
3000 fps

I've had some major issues with H1000. It's faster than posted here and on Steve's pages.
Here's what Hodgdon says:

"According to our burn rate chart, H1000 is faster than RL25, Faster than 8700 and just slower than 7828 but, you should keep in mind, that burn rate may change with application.
