No cartridge I own operates over 40,000 psi, so barrel burning is not something I'm familiar with. However, I'll note the capacity of the case compared to the bore cross section is similar to that of the .50 BMG. Is the .50 a notorious barrel burner (I don't own one)?

I recall Mule Deer suggesting one time that shoulder angle has an effect on throat erosion, so in picking a particular variant of the .22-06, one might want to consider that.

I'll further note this comment from Ken Howell, posted in these forums about 9 years ago:

No one has shot-out a .220 Howell barrel yet, but the significantly lower peak pressures guarantee a significantly longer barrel life.


His .220 is pretty much a .22-06, and you can read what he has to say about the "significantly lower peak pressures" in these posts of his on another forum many years ago.
