Can the barrels be made out of a much more erosion resistant metal? Tungsten? Yes the barrel would be expensive, but it would stand up to hot erosive loads for forever.
And it would take a forklift or a come along to lift the rifle! Tungsten is HEAVY! Course if you made it out of that, recoil would be almost non-existant!
