Pressure is immaterial. Let me say that another way....whether it's 11,500 psi or 5,500 psi doesn't make one iota of difference to the gun. If anyone is inclined to disagree, I'd like to hear the hear the scientific argument. Try that 11,500 psi down where the barrel walls are .025" thick & then tell me it doesn't make any difference. In the context of which "I Think" you meant it I agree, it doesn't matter.

my concern isn't recoil. It is the beating the gun takes.
I understand recoil is a factor specially when it comes to the wood standing up.
I just want to go easy on the gun. I am not afraid of a blow up or anything else. I have been at this for a while myself . I wanted technical input on operating pressures.
looking for whatever is similar to the RST lites in 2 1/2" without the cost. I don't handload at this time.

That the best you can do, Larry?
A little sophomoric to take "immaterial" out of context, even though I qualified it.
Mike, your words. You didn't say that pressure was immaterial "in a different way". You said something almost totally different, referring to SPECIFIC pressure levels. If you'd left off that first sentence, I wouldn't have bothered responding. I doubt 11,500 psi chamber pressure would do anything bad to a Fox, assuming good condition. Brian, RST will provide pressures if you ask them. Not sure about Fiocchi, but doubtful a load that light and at that velocity would present a pressure issue for your gun. I'd guess well below standard SAAMI 20ga pressure level.

In the context of which "I Think" you meant it I agree, it doesn't matter. Due to the time/pressure curve, that 11,500 psi is no longer 11,500 psi once it gets to a point in the barrel that is .025" thick. Chamber pressure peaks at (roughly) the chamber mouth and drops rapidly as the shot column moves down the bore.

The chamber pressure of a shotshell can NOT be extrapolated from payload weight and velocity. Claybuster alone lists at least half a dozen 3/4 ounce, 1100-1200 FPS loads for the 20 ga that well exceed 11000 psi.

Well said, Dewy Vicknair. I knew from studying your work that you're a patient man.

Claybuster alone lists at least half a dozen 3/4 ounce, 1100-1200 FPS loads for the 20 ga that well exceed 11000 psi. Nothing listed for guns in the States is going to exceed 11,500 psi by much, because 12,000 psi is the SAAMI service pressure standard for the 20ga. A shotshell manufacturer wouldn't want to cross over into that territory . . . just in case there were a catastrophic failure with their ammo.
