I can't find the link to Bob Baker's comments on this issue, but I have read a number of first hand accounts of Lil'gun causing throat damage when used a high pressures (60K psi+). My interest stems from my use of the 45 Raptor. I like the reported velocities people are achieving with the powder but I am not willing to gamble with a Krieger barrel. Too expensive for me to gamble with!
I use it at about that pressure in the 300 Blk, and so do about a million other people. I've never heard of throat erosion issues in that cartridge. It's not exactly known as a barrel burner, but then neither is most anything else that would use Lil'Gun in a rifle.
What cartridges did you read the first hand accounts about, and were they rifles or revolvers?
