US 869 Powder

[dig]

It has been a while since I have seen any information. This powder looks promissing in the 338-378 and 378 Wby. Any practical experiance.

Loads?
Extreem Spreads?
Standard Deviation?
Temp Veriation?
Ignition (Primers)?

Why is this powder taking time to catch? Any Good?

.Yes i used it in a 338 Lapau Imp. and i could put in more then i could burn in cold hunting temperatures. I could get 3137 fps with 300 Sierra. Shot pretty accurate at 1780 yards. Very dirty burning powder and when i took it out groundhog hunting in the summer it was really a hot load. Matt

very temp sensitive, my old sendero 300RUM hated it.

My 98B .338 Lapua thought that it was a wee slow even for the 300 Berger. It seems that it liked H1000 better. Went to H4831 for the 250s.
