Pressure loads
 

Hi guys I want to know if there is any evidence on breaking loads on barrels instead of just saying you can’t use modern loads or you will lose your face.
Is there actual evidence of pressure testing on a Parker barrels when they were made stating that there needs to be let’s say a 5 to 1 working pressure ratio?
As with Remington it is 55000 psi breaking load

Yes there certainly is evidence. You don’t get to be one of the most highly respected gunmakers in the the country, or even the world, if you didn’t have standards.
Every Parker made came with patterning tags with powder and shot load data including specific measurements. Anyone who chose to use greater loads than those specified on the tags did so at their own peril... to life and limb... or digits.

Ok great! Do you know where I can get the breaking loads ?
Thanks mike

Need the breaking loads for a titanic barrel?

There is no “one size fits all” formula. Each bore size and frame size had its own recommended load. In fact you could almost say that each gun was different, even though they weren’t, but “The Parker Story” certainly explains it a lot better than I can.

Ok so there isn’t a breaking load chart for a 12g.
I thought this information would be easily accessible due to safety

Please explain what you mean by breaking load. Do you mean proof load, or one that will definitely blow the gun up. I am confused in that i have never heard the term.

Sorry I mean what pressure rating did the Parker barrels fail? Then you can determine what low pressure is.

Read 'Finding out for myself' series of articles by Sherman Bell published in The Double Gun Journal. Excellent work reported on proof loads and gun failure. You will be surprised at the pressure required to cause failure.

Great thanks ile take a read ����
The reason I ask is because for there to be low pressure ammo there has to be a failing number to state that.
