His own cites show that the 380 has overall higher velocity than the 38. BUT he decided to be dishonest and post the LOW figures for 380, and the HIGH figures for 38. VERY dishonest!
I'll post some from others.

I really don't appreciate being called dishonest, especially since it was not warranted in this situation! I posted references for my information, and gave a summary of it that I believe accurately describes it
Here was my statement to which you seemed to take offense
Out of a 3" barrel, a typical 380 load will give 800-900 fps with a ~90gr bullet. A 2" revolver firing a 38 special +P will give roughly the same velocities with a 125-135gr bullet. The extra weight can give much improved penetration, and there are hollowpoints designed for 38 special that give excellent and reliable expansion in this velocity range(the 135gr Gold Dot is a good example).
Yes, there are exceptions to this, and this was why I used the word "typical"(Buffalo Bore it not "typical" ammunition) rather than "all."
In the interest of full disclosure, here are "real gun" numbers from the same reference I used with barrel lengths straddling the stated 3" value
Notice that discounting the Buffalo Bore +P, the 800-900 fps range is a fair estimate. Yes, some are higher, just as some of the 38 Special +Ps are higher.
And, once again, if we include Buffalo Bore 380 +P loads we should also include Buffalo Bore 38 special +Ps, which best the 380 by a considerable amount of energy.
And, with that, I'm done with this thread.
