The federal government has a test facility in Bells Corners (Ottawa). They test ammo.
They want 20 rounds per test. (That means 20 identical rounds).
I have not used them for 20 years, so have no idea what the current cost is. But it was quite reasonable when I used them.
However. the test result will be the pressure/velocity in a SAAMI spec barrel - not the pressure in your barrel. This can be very different. In the example below, there was a 6,000 psi difference between my barrel and a SAAMI barrel.
In the test shown here, the pressure was in one of our target rifle barrels (a Kreiger with an Obermyer chamber) not a SAAMI barrel.
If you want pressure in your rifle, this is easy to do. Fit the rifle with a strain gauge, and make/buy quality ammo to use as a standard.
Send the lab some of this 'standard" to test. let's say they come back with 56,000 psi. Then test the same ammo with your strain gauge and know that that reading is the equivalent of 56,000 psi.
Then test your various loads and note how much they are higher or lower than the 'standard" load. I did this for years until I sold the rifle with the strain gauge glued to the barrel.
