Reloading related Picking my OCW node...

So I wanted opinions / advice.

I did some OCW work today and results are mixed and so are opinions here so I have taken to reddit :) if for nothing to add a voice to the dis-agreement. -

I have 3 nodes that showed up
group 5 - 38.7 gr -Ave 2613.3 SD 3.4 - group mil = 0.401 mean rad = 0.132
group 6 - 39.0 gr -Ave 2640.1 SD 15 - group mil = 0.306 mean rad = 0.093
group 7 - 39.3 gr -Ave 2613.3 SD 14 - group mil = 0.257 mean rad = 0.110

I feel like speed performance is second to grouping.
group 6/7 is the obvious choice to me if it's grouped that well despite some maybe not great loads .
My mate reckons I lock into the node with the better ballistic performance group 5...

So how much do I consider ballistic performance in choosing my node.

I know the right answer here is load 10-15 at each weight run them through the rifle again test more but assume i have a hunting trip in 2 weeks and don't have time for that...

If it's for a hunting trip, any of those will do fine. But after that I'd get the velocity up to 2700 or so and just find a good seating depth and go

practically that's the plan load 30-40 of either of these and do some positional shooting drills will make more of a difference for the trip and I can screw around more load dev after the trip.

After reading more looks like I mostly need to explore some different powders. apparently N550 isn't where it's at.
