In comparing some FMJ 9mm to JHP 9mm, the outward appearance makes me think there's not a lot of difference between these two rounds that a 1/8"-1/4" drill bit wouldn't equalize.

So the question is, what would likely happen if you took FMJ's and drilled out an equivalent sized hole, then gently scored the sides?

I'm sure there's a good reason if nothing else based upon the price differential of the 2 different rounds, but it's not so obvious to me.
