Hi all, I went to the local gun store looking for powder for the New Vaquero as HS-6 is too position sensitive for my wants and 800x is all I could find. I loaded 6 rounds at 7.5gr and got a low of 703fps and a high of 734fps, that's great but POA was a little low so went and loaded 3 more at 8gr and got 756-783-768, I think 8.1 or 8.2gr will get me where I need to be. I have read reports of this powder not throwing well but in my Dillon 550b with the small charge bar it seems very consistent, not perfect but consistent. By the way this is a 5.5" barrel and a 250gr 12BHN boolit. I just thought I'd share my experience.
