LOOKING AT HAVING A BUILD PROFESSIONALY PROOF TESTED.
THOUGHT I WOULD START WITH SOME LINKS FEEL FREE TO ADD
GOOD INFO HERE
SAMMI WEBSITE. REALLY GOOD INFO HERE

Thanks I shot them a email as to if and how much??Quote:

seems to be very little on who does testing of this sort on the net.
If the ammo ( proof loads) were avaliable then one might be able to do some of this themselves. Im sure a improvised proof load could be calulated using reloading books and the such or contating a company that loads ammo who has done testing on there ammo.
It sure would be nice if the people at saiga would answer a few simple questions.
How much bolt thrust will a standard AK truniuon an bolt safley handel is all I need to know!
800 million of these guns built in several dozen countries and not one single piece of info what they will handel for pressure. it takes about 2 minutes to find what a AR is rated at. LOL
Soviet State Secrets remain secret. US secrets are all over the internet.
AFAIK, when destructive testing is needed, most manufacturers contract with HP White or do it in house. Prooftesting is also usually done in-house in the USA, we don't have government mandated "proofhouses" like Europe does. Most proof loads are either loaded by the gun manufacturer or are bought on a very restricted basis from commercial ammo makers. You can bet Colt and Marlin have tons of signed agreements with CCI or whoever before they can buy any proof loads. Same goes for load data, someone somewhere would sue.
I got a reply back from HP white. they charge $600 for the service.
IT WOULD BE NICE TO HAVE SOMETHING LIKE THAT DONE BUT ITS OUT OF MY BUDGET.
THEY DO NOT SELL PROOF ROUNDS UNDERSTANDABLY.
There are several pressure transducer setups out on the market now, in the $600-$700 range last I looked. You glue the sensor to the chamber area, shoot, and a USB doohickey samples the signal and sends it to a laptop, running software that generates a nice graph for you.
They're also reuseable, so you can use the transducer on multiple firearms, or all day while you're developing loads.
Expensive, but you can use them over and over, like a chronograph.
I recall the one I priced was $300 assuming you just need the transducer and software. I'll supply my own laptop computer :) I was planning to get one of those sometime I have a chance to actually do some more testing.
Thought it was this one:
Ballistics Software, Chronographs & Pressure Instruments For Shooters
... however they only advertise their 2.0 wireless-only solution. I guess they have upgraded since I last priced them :(
You can use this information to compare to known loads as well. QuickLOAD software reportedly has pressure information attached to their application but I have not used it.
