6 BRX how to break this down?

[Lefty Trigger]

End of the day last 11 rounds are fireform rounds and shot this 11 round group. Here's the break down of the load...
Ran out of Nosler 105 RDF's so used Sierra 85gr HPBT bullets seated .020 into the lands.
Lee dipper scooping Varget powder, have no idea how much? It's over 30gr and under 31gr
Federal 205 standard primer
Shot this crazy accurate 11 shot group. Just put away the LabRadar so have no idea on the speed and this was the last 11 pieces of brass to fireform, dang it!
These was shot out of my 29 inch 7 twist at 100 yds.

Do you have a picture or the rdf bullets?

The Noslers? No. I had about 200 of them left and never could get any decent results so I quit reloading them. When I got the BRX I used them to fireform my brass, well I ran out of them and had to use the Sierra 85gr HPBT bullets to finish up and those shot this group.

Your rifle doesn’t seem to like those Bullets or powder

Hard to believe a "thrown together" load like that would shoot that good. Now to try to figure it out and duplicate it....

I’m still trying to figure out why my first wife let me.

Now start over

The Sierra 85 just plain shoots! I used a ton of them oin XTC in my 6mm woa, then my 240 Tomahawk for short line. Both fire forming loads and standard loads. I use to just drop my slow prone powder charge in and shoot that way. Not as fast as I could have pushed them but boy did they just hammer!
