Well if a 3 ton (6720 psi) crusher service pressure is equivelent to "10,730 psi (service)" that means it gained 4,010 psi (+60%) in the conversion. I for one am not sure we have all the last words on this subject. Personally I believe the 8960 psi figure is much more realistic & on those guns proofed to 1 1/8oz or 3ton I will stay below 9,000 psi.
