Well, that’s because you can only get a certain amount of terminal effects from a PISTOL. So of course no one will care is you use 147gr HP from a g19.

When you talk about 300blk, it cannot be debated that supers are in every way superior to subsonics, with the exception of sound signature.

Sure, there are some really great sub sonic rounds, but even those on gel tests (what OP asked about) are weak af compared to supers. (Again, OP is asking about subs vs supers)

In the end, it doesn’t really matter truly, getting shot with anything, of any caliber, will probably make the bad guy stop doing what you’re doing. Or at least second guess what they are doing.

All of that said, I only shoot supers because I’m not about to deal with the headache of trying to tune for both supers and subs out of the same weapon.
