I was able to fire my 70gr Varmageddon test rounds today. I used MP 405 (N133 equivalent) and IMR 4198. Here were my findings:
All strings were 3-shot strings. All strings were under 0.8 MOA.
MP 405: 25.8-27.0gr in 0.4gr increments. Gun did not cycle properly, but occasionally cycled a round through. I did notice in the Hornady PDF had 65gr with N133 data maxing out at 29.1gr, but for whatever reason I played it real safe. I will definitely push it out harder next go-around.
IMR 4198: 22.3-23.5gr in 0.3gr increments. Up to 22.9gr bolt never attempted to cycle. Past that it attempted, but failed most of the time. Anyone have any data with IMR 4198 and 70gr projectiles and how hard they were able to push it? Lyman 50th in 6 PPC showed max compressed at 23.5gr.

The moment you've got it figured, you're wrong.
