I have been working with retumbo and the 216gr clinch river in my 300RUM and have been disappointed in the last 2 days.

Last summer I had .2moa and now in the past 2 days, I have run the ladder from 87gr-91gr and have not gotten anywhere near as good. Anyone have any proven loads for this combo?

i've found a sweet spot with my 300rum, only using 200g accubonds 93.0 Retumbo col 3.60 3240fps at 3300ft elv. 3 shot groups .75"

skidly, what was your barrel length for that velocity? I got that with the 200gr SMK, but I was using a 30" barrel. It would appear I need to maybe step up a bit in powder charge.
