Progress update:
At it again and this is the result:
Sighting check and fouling 2 rounds (grid is 17mm x 17mm appro 3/4") :

So I was pretty happy with that start. Again these were the 55gr V Max with 32.5gr 2206H. So onto the main show of loads. I use this perspective to clear away the distractions of the data and just look at the shots:

And from the front:

So some pretty encouraging groups, esp at 30.5gr and discounting the odd one at 34.5gr, that looks promising. Some more work needed.
So Im not sure where this puts the discussion on twist rate for the 55gr pills, esp with the sighting shots group, and the 30.5 gr group. I would anticipate looking at these two, and maybe the 33.5 a little closer. I also have a load devel. batch with ADI 2208, which many have said in other threads is a 'better' powder for 22/ 250. TWT.
Thoughts on this latest set of groups welcome.
And just so you know I was shooting pretty well there is this with the 22LR @ 50 m.

Thanks in advance for comments and thoughts.
