[QUOTE="Mikecr, post: 3069551, member: 1521"] I can't watch the video from here, but high pressure, and pressure 'problems' are separate and different. With a plan, you can build a gun for higher pressure, and yeah a BAT would be a good part of the plan, due to strength of the lugs/action overall.. For the brass part of the problem, you would likely need to rethink what you think about reloading. I doubt 100+Kpsi would be useful over ~75Kpsi competitive short range BR loads. That is, with brass cases. But high pressure can be very useful (for way better than just MV). It reaches into diminished returns (a flattening of the peak) which usually equals diminished variance of returns. You might see an example of this without extreme pressures; People find that firing a normal load with new/unfired cases, can produce results that are more consistent (and better) than the same with FF'd cases. This is because some of the pressure peak is consumed (flattened) to expand the new cases. Well an action & chamber can also give in like this, with high enough pressures, and this can be considered in the build plan. Bruce Thom (BAT) helped me once with an action choice for a 26wssm. I went into it thinking 'short' action, Bruce convinced me to think 'magnum' action. Get the appropriate barrel steel around that chamber. He was right. Combined with a fitted chamber (to new WSSM brass), I could viably/long term run pressures at 75Kpsi+. [/QUOTE]
