Hi Stuart,
Not sure what any one else thinks but I reckon you had better stop testing..... your 30.6 & 30.8 loads have returned sub .5" groups  at 200 meters and your velocity is over 2940 fps.....your problems are over!  
These loads should easily go sub 1" at 300 and that is about all I ever look for at that range with these types of bullets as sub 1" at 300 means it's theoretically possible to go sub 2" at 500.....if you could shoot all your targets sub 2" at 500 and keep them centred you'd win every match you entered.
The info from your chrony will be valuable to compare different powder lots & bullet lots etc, so keep it all.

Regards,
Belly
