    Just wondering if anyone is using this powder, and what your results were, favorable or not for accuracy. I was going to try it in my 7 SAUM w/ Winchester Mag Primers

    I loaded it in a friends 270 Winchester. 55.0gr's in RP brass, CCI LR primers, 150 gr Hornady SST's, seated at 3.285". I haven't put many down the tube yet, wanted to simply do a function check to make sure it would shoot, as I had a little trouble reloading it to start. Everything worked out well, no chrono yet, but simple accuracy tests were promising. I need to stretch it out a little bit, find out if I want to continue going this route for the rifle. Meters phenomenally, very consistent. More testing will be done, but it is for a factory rifle, completely bone stock. Its a Ruger All American.

    I loaded it in a 6mm-284 shooting 105 A-Maxes at about 3200 if I remember correctly and accuracy was very good. I didn't put it on much paper but it did well to past 800 yards on prairie dogs this summer.

    I tried it in my 7STW and 300 WSM.As far as I could tell,it shot the same point of impact in those rifles loaded with Reloader-22 and the velocities were also about the same.Accuracy was very good.

    Thanks guys, I just bought 4 pounds and really like the fact it meters through my Harrel's powder measure within .1 gr.
