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 ( 2500 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

Yes. My apologies. Should be 2500 fps.

Henlo.
For all intents and purposes you are on a node. Prediction is for 27.5 grains of your current batch of S 335 for MV 2512 fps - 15 fps for the chrony at 5 meters. This batch of S 335 is burning slow in your rifle. Start with a much lower charge if you use a different batch of S 335.
How was your grouping ?

I shot three 123gr lapua scenars today to get a speed for calibration, everything was kept the same but I loaded them with 26.3 gr S335 at the same COL and got the following speed: 2381 fps 2352 fps and an error, could you check what the node speed is on them. I am deciding between the two of them
