After casting around unsuccessfully for a stainless Colt in 38 Super last year, I settled on a stainless Kimber Target in 38S. I really like this gun. Then a local smith installed a 9x23Win Kart barrel. Side-by-side the cartridges look very similar, but Wow at the difference.
The first time I shot the 9x23Win at the range, I noticed I was being covered in white flecks. At first I thought it was dandruff, then the flecks got larger and larger. I kept looking at the gun and ammo. I couldn't figure out where the "snow" was coming from. Then it hit me. The ejected cases were striking the particle board partition just over my right shoulder so hard that the cases were digging up the painted wood !!
