Just picked up some Buffalo Bore non +P 38 spl 158 swchp. I liked the idea of the old FBI load at standard pressure/low flash and it got me to thinking. Even though the load is lower pressure would not the "thump" (for lack of a better word) to the gun be the same as the old FBI load being that they produce the same energy? My thought on this load is that less blast/flash from the lower pressure are good things in a defense load. That's why I bought it. I just don't see how it can be much more gentle on a gun than +P.
