Pressure testing
Had a weird thought...is there any place you can send your handloads for them to test and send you back the pressure results?

Yes, but the data would only apply to their test barrel.

Seems as if that would be true of any pressure data we see in our manuals.

Yea and if they are using a universal reciever that has a closed breech and your using a revolver, with a b/c gap the data would not even be close.

I know at one time Western Powder would do piezoelectric transducer pressure testing for individuals. IIRC, the cost was about $50-$60 for 15 rounds.

You could buy RSI Pressure Trace for about $450.

Good engineers sometimes hassle anyone with a question or a task by repeating the same question over and over, "What is it you really want to do?"
A fall out from that might be, "What if you knew the pressure? What are you going to do? Compare it to SAAMI registered values? What will that do for you?"

I don't see why some responders are questioning the value of having H.P. White Laboratories (or some other similar commercial ammo pressure-testing company) test handloads. The data is no different from what we see in the reloading manuals that we all use. Except, it is exactly what we are using, instead of a recipe with a bunch of component substitutions.
True, it isn't OUR gun's pressure, but OUR gun is supposed to be SAFE with whatever meets SAAMI pressure standards in a SAAMI-spec'ed test barrel. So, using H.P. White for pressure testing our handloads should provide an even better measure of SAFETY than simply following a recipe with the same components, but different lot numbers. And, when there is NO recipe, then such testing makes real sense. And, we already have our own equipment for testing performance (chronographs, targets, and ballistic gellatin). SL1 |

It was really just a curiosity thing.
It would be kind of neat to know what exactly is going on internally. We get chronos to clock how fast our loads are going. I guess pressure testing our handloads would be just another stat we could pay attention to. I realize its a bit more in depth that a chrono and that there are published loads for a reason...like I said it was just a curiosity thing. |
