Quickload and lack of pressure sign @106K

[constructor]

I am shooting a barnes solid with 3 grooves in it.
The barrel is 11" twist.
The 28 gr load of RE10x is compressed heavily.

Quick load says my pressure is 106K !!!!
There are NO pressure signs. No case expansion, No flat primers,
no swipes, no leaking primers nothing.

Do you think the slower twist is lowering pressure?
what about the grooves?
what about the compressed load?
all 3 together?
Has anyone experienced this before?

After running more test and comparing signs on other loads I've come to an answer. I think.
With 110vmax and 115SMKs Quickload hit the velocities dead on with the charge I used. Pressures in both cases were 65000+- when signs appeared.
With both barnes bullets the velocities were way off 130-190fps.
working backwards from 30.5 gr to 29gr I hit the velocity I had in the field with the 110 TSX and 66000psi. It seems that I am getting 13000 psi less than QL shows and also less speed.

What about your start pressure in QL? Are your bullets jammed into the lands, or not? Might be part of the problem.

There differences in each batch of powder. I have run into instances were the reload manuals and Quickload say a certain powder charge produces a certain velocity/pressure and I find that same velocity several grains higher. I also have a pressure trace and try to confirm the load is reasonable. Ken Oehler,maker of the chronos and test equip) says the brass and primer signs don't always manifest themselves as most people think they should. He has personally had his hot loads show high pressures on a borrowed meter but not in the brass and attributes his survival to generous safety margins built into the gun.

I have heard it said that as long as you meet the velocity listed in a load manual then you aren't likely to significantly exceed the pressure listed either. Still, unless you have a pressure measuring device and can compare a factory round vs your reload I would say you are in danger of blowing up a gun.
