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.

Hi Dale SH
Thanks for your mail.
I'm sure about my 1.5 mm jump
Please help - what did i do wrong.

Thanks.

[Dale SH]

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 ?

[Jay Jay]

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

[Dale SH]

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