At some point you reach a point of diminishing returns.
A few years ago some shooters built a .223-.378 Weatherby Mag.
They wrote a piece for Precision Shooting mag.
The barrel lasted about 95 shots before being toast.
The .224 cal. bullets were doing about 5050 fps. I can't remember if the bullets were self-destructing or not but I would think that they were.
Here's a link to another forum that I found where they talk about the
.223-.378 Ergensplittin Loudenboomer.
God and the soldier we like adore,
In times of trouble, not before.
When troubles ended and all things righted,
God is forgotten and the soldier is slighted.

When asked for my race, I answer CauCajun.
Hope is not a plan, and not all change is good. The resistance is here; the resistance is now. RESIST!
These hands are neither cold nor are they dead!!
