Anybody try US-869? It's a bit too fast for my 7mm AM, but I load 110-111 grains of US-872 powder in it behind a 175-180g bullet and it works great.
US869 works best with 160 gr bullets in my 6.5 Prometheus, can't wait til Berger release their heavy 6.5mm bullet, hope they don't go lighter than 160 gr, all them 6.5 Crudmore shooters have enough bullets as it is, we need heavies man !
RL 50 worked great with 230 Bergers in my 300 LRH and will be trying it in the 7mm LRH after the RL33
US872 ? prolly meant WC872
