Classically we "write off" the FMJ as a poor performer compared to JHPs. I was looking up some stuff in M&S's "Stopping Power" book and ran across this.
Before I say this, let me state that NOBODY, including M&S is promoting or teaching OSSs.
Having said that, the highest 9mm JHP OSS percentage is 91% and some of the top performers come in at 88% and better, but the lowly, ineffective 9mm JHP had a OSS rating of 70%. 70% doesn't sound so shabby to me! A bullet that stopped the fight with one shot 70% of the time? How is that bad? Especially since we're likely gonna be shooting more than one shot.
This'll light some fire, but the three 230 gr .45 ACP FMJ bullets listed only had a 62% OSS percentage.
Any thoughts? Preferrably not about 9mm vs .45, seems like we've already done that, but about the effectiveness of a 9mm FMJ vs 9mm JHP.
