Your 27.5 grain load is on an accurate node.
How was your accuracy ?

Henlo.

I disregarded the 2542 fps shot from the 27.5 grain load.
I think it was this shot that flew high and disrupted what looked like it could have been a good grouping with your 27.5 grain load.

If I disregard the 2542 fps shot and use the average of 2513 and 2516fps and add 15fps for the chrony at 5 meters then as I said your 27.5 grain load is on an accurate node.

MV should be 2529fps - 15 fps on the chrony at 5 meters = 2514 fps average.
Thus my reason for saying that your figures for the 27.5 grain load are right on an accurate node.

Thank you, I shot the 27.5gr load again today, but the extreme spread was bad, 77 fps over 10 shots, temp was almost the same as yesterday, might be S321. If I use S335 wil the node speed be the same or lower?

Depending on the batch of S335
Predictions are that your node speed will come down by about 25 fps ( 2700 fps average MV)
Your case fill (with the 108 Scenar and your current COL) will be almost 100%
Your percentage of powder burnt will increase substantially to almost 100%
Pressure will be almost the same at 48200 psi
