760 Pumpmaster Chamber Tube Pressures?

Has anyone been able to measure the piston/chamber tube pressures inside a standard 760? I have seen people claiming around 1000 PSI, but it's always been kind of hearsay and I'm hoping for some hard numbers so I can figure out some safety allowances.
Thanks,
Kevin

There is a thread on 13xx/ 2289 piston testing that will tell you what you want. Stock 10 pumps looks to be around 750 psi. With a flat top piston and valve you are looking at around 1000 psi with 10 pumps.
