9 vs 9 plus p?
lots of encouragement to plus p ammo, but anyone know a link to actual testing and comparisons between the 2? what is diff. in penetration and
expansion of 9 and 9+p in ballistic gelatin or through jugs of water?
I've never understood why some people think 100 fps is a big deal going to +P or +P+ but that another 100 fps on top of that is no big deal...The difference is not enough to be concerned about one way or the other. The main difference between 9mm and 357sig is velocity. Many will say the 357 is superior. 9mm +p and +p+ make the two overlap in performance (best 9m vs slowest 357). Comparing the Federal 9BP vs 9BPLE, when both are available I will pay the extra $1 per box for the faster ammo.
Because it takes a significant increase in pressure to get to that marginal increase in velocity. At some point you hit an aerodynamic wall where returns diminsh greatly.I've never understood why some people think 100 fps is a big deal going to +P or +P+ but that another 100 fps on top of that is no big deal...
