My barrel length is 26.
My results;
85.6. 2949fps. SD 7.9
86.0. 2952. SD 18
86.3 2963
86.6. 2989. SD 11.3

The 338 Jarrett has about 2 grains of capacity over the 340 bee.
Accuracy across the board was under an inch, though the rifle doesn't like having the chrono hanging on it.
Come ups from my 200 yard zero for 400 yards indicates the chronograph was accurate.
What, if anything, does this information give you with quick load?
