To me this is the most aggravating part of the deal there. I've recently ran out of IMR 8208 XBR for my 6.8spcll. I'm having a really hard time finding a powder that's even remotely as accurate as it. Last time I went out and tried some Alliance A2200 and it was all over the place and it seems to be a really popular powder in the 6.8 SPC forums and from some guys on here as well. But it looked like I shot the target with buckshot it was so erratic. Of course everybody's gun is different because of barrel variations but it can be a really frustrating part of reloading.Well, it's the 'boring' part of the process. A lot of time and energy seems to go into talking about powder loads.
