Gents,
Looking to find your perspective on the Muzzle Velocity I should try to obtain in my .300 WIN MAG
In doing my research here, the overwhelming number is 2950 fps, but my question is how do you know where your number should be?
I've had some time doing the barrel break-in on my AIAW . 300 - I started at 67g and Im now at 68.6 with a resulting corrected velocity at the muzzle of 2881 fps.
My groups are good - Shot a personal best 5-shot of .252" today, and have recorded (12) 5-shot groups that gave me an average of .435". This should be the average +/- 12%, 95% of the time if I can do my part.
Here is what I want to do:
Im not a bench rest guy and as soon as I get my information and dope correct I'll be looking to just shoot steel. I'll probably shoot a few local matches so I'll need to be able to group, but that's not my priority for the rifle.
The gun will be used from 600-1000 yards 90% of the time and I'll be able to stretch it to 1300 yards twice a year.
SO....
Do I keep going and try to reach 2950 and watch to make sure my accuracy doesn't go south in the process or signs of pressure show?
Or:
Do I wrap it up now and start to get my dope?
Sorry this was so long...
Your thoughts are appreciated.

BTW:
IMR-4350 - 68.6g (At this point)
Winchester Brass (Prep'd)
Winchester LRM Primer
Sierra 200g Match King
.010" off the lands
Out of a 26" 1:11 .300WM Accuracy International AIAW~
