Has anyone ever posted a thread trying to achieve 380 velocities shooting a 9mm?
From a handloader's point of reference, pulled out my well used Sierra #5 manual. For an expanding bullet, their recommendation is a 90gr JHP for the 380, max MV ~900fps, 3.25" barrel.
9mm, same 90gr JHP, 4" barrel; lowest powder load MV ~1100fps, max MV ~1400fps.
I have no idea who this person is who states 380 penetration is within inches of 9mm penetration; main point being that inches is plural and not singular.
In my mind, 500fps is a significant difference when comparing two calibers. From a velocity standpoint, the 9mm 147gr JHP is faster than the 380/90gr JHP and will penetrate "inches" more than the 380.
This expanded, handloaded 147gr Gold Dot chronographed 1150fps thru a G17, penetrated a redwood 4"x4" piece of wood, a steel washing machine lid, a cow rib and completely ruptured two 2 liter bottles filled with water.
The 380 doesn't have the momentum to run with the 9mm.
