Why it matters: The oldest argument in handgunning consumes oxygen that better questions — about shootability, practice, and load selection — deserve.
Every hobby has a theological dispute, and handgunning's is caliber. It had a factual basis once: mid-century service ammunition really did perform differently across bores, and the institutional studies that followed were contradictory enough to keep every faction supplied with citations.
That world is gone. Modern defensive projectiles are engineered marvels, and when Terminal Velocity Labs runs ten current loads through calibrated gelatin under FBI protocol — bare gel, heavy clothing, chronograph verified, blocks recalibrated on camera — the envelopes overlap almost completely. Penetration spread is wider between loads within a caliber than between the calibers themselves. This finding has now been replicated so many times by so many independent testers that continuing to dispute it is a hobby, not a position.
Why short gel tests still matter
So why does the war continue? Because it was never really about terminal ballistics. Caliber allegiance is identity — generational, tribal, sometimes just the sunk cost of a safe full of one headstamp. There's no shame in any of that. The shame is dressing it up as physics.
Here's the liberating part: once the terminal question is settled, the real questions get interesting. Which platform do you shoot measurably better on a timer? Which ammunition can you afford to practice with monthly instead of annually? Which load has documented performance from your barrel length — a question this same channel's barrel study just made answerable? Those questions have personal, empirical answers. The caliber war has neither.
“Continuing to dispute it is a hobby, not a position.”

The data won the war. Let it also end the occupation.
For context
- The modern era of public terminal-ballistics testing — calibrated ordnance gelatin, standardized protocols, published raw data — has produced converging results across independent creator labs for several years running.
Themes in the source
Room for disagreement
The honest residue of the debate: margins exist. Barrier performance, intermediate obstacles, and capacity-versus-diameter trade-offs are not fully identical across calibers, and specialized contexts can justify specialized choices. But margins are what they are — margins — and the burden now sits with anyone claiming they outweigh the documented, dominant variables of shooter skill and load selection.
The bottom line
It was identity wearing a lab coat. The lab has spoken; keep the identity, drop the coat.
