Sorry if I sound like a stuck record but how sure are you about your jump ?
Your lowest load is at 65000 psi and your burn rate is indicating that your bullet is in the rifling.

I regularly assist a friend of mine with his Howa 6.5 Creed and 143 grain ELDX bullets.
His max COL is 72,4mm and we load at 71.4mm
74.42mm sounds a bit long.
How did you measure your jump ?

My max is 74.42 mm - measured with a Hornady Tool
them I took 1.5 mm from the 74.42
I've then loaded my bullets 72.92 mm

Try load at 72.0mm and 40.0 grains and see what your results are.
