I picked up some Berger 300 Hybrids, had a hell of a time finding data... So I finally decided to contact Berger...
The Following is what I recieved...

Bullet | Powder |Start Load|Approximate Start Velocity|Max Load Approximate Max Velocity|Fill Ratio
300 Grain | RE-22 |74.5|2469|78.5|2538|93.4%

300 Grain | RE-25 |77.5|2485|81.5|2597|99.0%
Now, my question is: Where are some of you guys coming up with your loads?
I ask because there has been a few gents on here with 90+ grains of H1000 or RETUMBO... I'd like to know where I can find this Load Data or if I should stick to Berger's recommendation...
Any advice would be awesome!
