There's a local guy that has set up quite of few of these guns and his load data is:
Nosler Brass
Berger 140 VLD hunting
52 Grains H4831SC
CCI magnum primers
Does this seem like a good starting point? Should I load some more of these and just shoot !
Yes, this is an excellent starting point. Good accuracy and low velocity spread. Where you go from here depends on your particular needs. You can certainly use this load for shooting, hunting, and familiarizing yourself with your new rifle. At 2800FPS you are not exploiting the full potential of the 6.5x284 which should be capable of delivering the same accuracy and ES of your current load with velocities in the 3000FPS range. For hunting you can achieve 1000FP of energy at 1000 yards as opposed to 700-800 yards at the lower(2800-2900} velocity. With H4831sc you will likely run into high pressure at 53-54gr and max out velocity in the 2900FPS range depending on your barrel length and characteristics of your particular rifle. If you desire to improve your energy your should be able to use a slower powder like Retumbo(56-59gr) with the same bullet, seating depth, and achieve comparable accuracy and ES at 2950-3025FPS while maintaining acceptable pressure. IMO
This is the results of my recent build and third 6.5x284. Velocity is 2975FPS/ ES <10FPS.
