This is in regards to the back and forth between the 7.62x51mm and .308Win debate,commercial and handloads PSI readings.
A few weeks ago I had FedEx'd a commercially loaded 175grn Federal Cartridge Company 7.62/.308Win round and a 168grn personal handloaded.308Win round to an Armory here in town with the intentions of having both pressure tested in one of their testing facilities.
(The commercial round is the exact same product supplied to the U.S.Military,using 41.7gr of IMR4064) My handload has exactly 41.7gr of IMR4064 as well.
I explained my reasons and paid for the testing. I was emailed the results earlier today and was pleasantly surprised.
The commercially loaded 7.62/308,(remember, this is the same crap supplied to the military) had a PSI of 45,937.5
My supplied handload had a PSI of 44,346.7
This is from one independent company and their findings and is not to be taken as an end all be all but makes for good cannon fodder when the debate arises again...
