Bolt Group Buy - Possible?

[cory]

Nobody should be loading for the Grendel in the AR15 past the maximum published loads. 62,000psi is about 10,000 psi more than max loads. The bolt thrust and bolt geometry of the AR15 bolt barely support 62,000psi pressures that long in 5.56 NATO.

While this is true, the bolt still needs to be designed with a Factor of Safety (FoS).
Factor of Safety=Ultimate Load/Allowable Load

I've read here before were Bill A had said he had to proof test the bolts to 62ksi. This gives us a FoS of 1.19.
