As stated before, Winchester 1885 High Wall, .300 H&H Magnum, 28 inch barrel, 230 grain Berger Hybrid, right now using R-P brass, with 215 primers.  At 65 grains H4831, average velocity is 2607fps... Berger load data for 24 inch barrel says 2610fps for 63 grains H4831 (which they list as MAX load... however, others list 67grains as MAX and I"m seeing zero pressure signs).  Accuracy is great, precision is great.  In a step function, I moved up to 66.25 grains... Berger says .  2647 fps, still accurate and precise.  I think I'm going to move back to 65.0 grains and stay there.

WHEN can you say you've EVER known me to "just fall asleep???"... hhmmmmmm???

I'm having to relearn things I never expected or really wanted to.

The velocity your getting seems reasonable to me. Berger is likely testing loads with a custom barrel and a more precise chrono than the average person has access to. I’ve compared my chronograph to other people’s and gotten as much as 150 FPS difference. To me, getting consistent velocity is more important than getting high velocity.

I use two chronos... MagnetoSpeed and LabRadar... they are very close on everything else I've tried.  Big difference to me is 24 inch barrel (load data) vs 28 inch barrel (my rifle) with larger powder load.  Just not making sense to me right now.

Just tried 3 rounds (yes, I know, small set, but thunderstorm moving in) with the MagnetoSpeed at 65.5gr H4831.  2674, 2668, 2674.  ES 6, SD 2.45(approx, rounded up), under 1 MOA.  I can do better, I was in a hurry shooting because it was starting to rain.  However, I'm MUCH happier with what I'm seeing for velocity and spread... maybe I've not really broken in the barrel, yet...  
I'm going to drop the load back to 65.0 grains.  If accuracy is as good or better, I will stay there.  

Thank you for your advice... it's been great to make me spin the mental gears.  Truly appreciated.  I'll need more...
