Here is the latest update.
More prone in the snow, 31 degrees
Airing them out to see how they do at distance
3@300 yards 4" group
3@500 4" group
3@600 6.25" group
They seem to be doing around 1 MOA even out to 600. Not too bad from a factory Rem 700 that goes 7.5 lbs all up.
We need some more...
All shots are from prone in the snow so take them for what they are worth.

1.5" group. I am pretty sure I pulled the last one. There were 2 together and one 1.5" out.

Yes, but I don't think they show too much. Need to experiment more. With the 4350 it seemed to tighten up as the charge weight went up. I will have more results later.
Could not resist trying these. Here are some early findings

After getting the most popular weights taken care of I would like to play with a heavy (around 120 grains) .257 with a true bc of at least .5.
Seems like something like that moving at 3200 fps would be most impressive.
