H-870 powder is there any left

H-870 was a US Government surplus powder which the government stopped using it.
Check with www.gibrass.com AKA Jeff Bartlett. He stocks WC872 ball which the original application is U.S. 20mm Vulcan ammo. WC872 uses same data as H-870. Jeff Bartlett also carries WC860 which I believe is a pull down powder. I tried both in my 338-378 with great results. The WC860 seemed a tad faster than the WC872.

Mike,

When cleaning your 338-378 try running a patch saturated with some kind of light oil, such as 3 in 1 or other light oil through the barrel after extensive cleaning and before your first shot. This procces works best if you have a very clean metal surface in the bore. What this does is lubricates the first (foul) shot and reduces the overall fouling in the long run. In MOST cases one can expect to double their shots between cleanings before accuracy goes AWOL.

I only have about 40 pounds of the H870 remaining and about 100 pounds of the winchester WMR powder. Both are excellent powders. The WMR is the best I have found for the 338 lapua and the h870 for my 338-378. I guess I need to save the good stuff now for serious shooting only.
