I picked up some 40 gr Nosler and ran a ladder with 8208 and Benchmark. The 8208 was best as i figured and was a little surprised it got as high a velocity as it did. 4141 fps was the highest velocity. Primers looked great .
The short oal (.100" jump) , light bullets and +3 gas system would not let bolt cycle far enough to eject and or feed. Would need to open gas port so will shoot these in something else.
Accuracy was also surprisingly good for such a long jump. 3 shots .46" ctc @ 100 yds.
I also took an IMP case and necked up to 6.5 to see if I thought it would be worth building one. I can get roughly 3 gr more powder under a 95 VMAX (30 gr BM is compressed according to Hodgdon) so should be worthwhile to build one. I hope the Ruger predators chamber is small enough to be able to be cleaned up with my IMP reamer for a direct comparison.
