setback!!
thanks byron, took a minute to find that thread, but he shows that setback from the smiley does increase velocity and therefore pressure. But still no way to correlate the 2 values.
The safety factor of a P3AT barrel is not much based on my old guesstamit calcualtions. And one guy on that thread said he is handloading .380 'extra hot' because he likes the recoil. If he gets a good smiley someday, he may get recoiled to eternity.
Several others said they are not going to file their feed ramp 'cause the factory should have done it.
Well, time will tell.
"Whatever", "Duh",
