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!
