  Phil Sharpe shows loads giving between 33,400 &40,700 psi using 3031 and 4064 powders. Bullets were 46 and 56 grains. According to Sharpe,
  Winchester recommended that max loads should be kept below 40,000psi.
  Both Ackley and the NRA handbooks give loads but neither give corresponding pressures.
