Do you find charge weights, pressure signs, and velocities to be similar or different between these two powders?
Is US-869 noticeably slower than AR2218?I used my entire lot of 20lbs of US869 in quick time developing my 416 Rigby Improved rounds, this was recovered powder and not the canister powder.
I've never had access to the others mentioned, however, H50BMG is in ample quantities here and everything was extremely similar between the 2, so when I ran out of US869, I wasn't disappointed. However, you could fit more US869 without vibrating than H50BMG, which is called AR2218 here where it's made.
Cheers.
No, very similar, but the density is very different. I found it dirty when lower than ideal pressures were at hand and it is temp sensitive.Is US-869 noticeably slower than AR2218?
