It depends on the seal you're using, I had some seals in my HPA BBMG prototypes that held at 850 psi
this particular seal I'm using is 4mm internal diameter silicon tubing, I think I had bought it from a pet store, the sort of thing they use in an aquarium, so it shouldn't be hard to find. It is affected by the internal diameter of the seal vis a vis your projectile diameter, as well as how much the seal can yield (depending on material thickness and hardness).
