I get 3050fps from H4831 and Barnes 130TTSX at about 60gr. Could go higher but accuracy was so good it didn't seem worth it. This from a BACO FWT. Tried several other powders and some of the new Enduron stuff and none of it was as accurate as the H4831.
My next endeavor is ELDX and RL26 if I can ever find some.

I am continually astounded at how quickly people make up their minds on little evidence or none at all.
