Overpressure?

[WeiserBucks]

If it's on a Remington action , primers will show catering at low pressure. Get it into the normal velocity range and adjust accordingly for accuracy, SD and brass life.

Measure how much the case head has expanded from new of fire the load and see how many loads it goes.

My Win model 70 in 7WSM makes that level of cratering with every round. From other reviews, it sounds like some clearance around the firing pin. I try to avoid hitting max loads with this rifle and have had no other issues.

Just buy and install PressureTrace and you will know.

barrel length?
H2O capacity of fired case?
COAL?

If you have those on hand, i can run it on quickload for you and get you a reasonable ballpark idea of pressure

How expensive?

A bit more $ than I'm willing to spend. Could be nice though.

I have one, well worth the money and shows that QL is almost always off by at least 20,000psi in most cartridges.

Case head embossing from deep machining marks on the boltface will start at about 50,000psi in my experience, far from max loads.

Cheers.
