Thread: Wilcats and Pressure

I wouldn't have a clue what pressures I run my rifles at. Most are sorted at 2 grains less than first signs of pressure on new brass. (I don't load more than 55grains of capacity at the moment) Most of my loads exceed listed maximums from reloading manual and supposedly max safe loads. My GS custom rounds exceed by quite a margin without pressure signs. Why is that approach not sufficient for any workup?

Will a 70K psi figure released from somebody's strain gauge mean 70K.... or it could be 85 or 55 in reality?

If I blow up one action in testing to determine failure point, on what basis can I use that information to realistically establish the safe working load of other actions produced by the same manufacturer... whats the probability of my sample of 1 reflecting the average population all all other production for that action from that manufacturer...?

Some actions are known to be stronger than others.... how have we established that in the past....?? By load development in the action... whats changed? The only thing you don't know with a new cartridge is the starting point, but that can be worked out.... after that it all gets really similar?

Build your own safety margin in......
