Is it?

This is what I’ve thought would be a good idea, as a non-engineer, for a while. Basically, it’s a pencil profile except for a ton of extra mass near the chamber. For a “combat barrel,” this seems to make sense to me, though I wonder if a simple pencil is just as good for less weight. For anything precision, I’m going to guess that it is inherently less precise than a Hanson or Core tapered profile.

So yes and no, if I were to guess.
