I'd say that's looking pretty good! I would play with charge weight a little more, up and down, and see what I got. Do you have a chrono? I certainly wouldn't give up on Varget without some more experimentation and, preferably, some chrono'd velocities. I don't have a chrono myself. I have got to fix that one of these days!
I do have one but i broke it a few weeks ago. I was using a friends today and it wasnt picking up very well at all. I have to get another one. I think im loosing 100fps using Varget over some others. Im going to reshoot my good groups but with 5 shots and if they hold together ill stick with varget and tinker with another powder later. The fps is written next to the groups.
