Throat Erosion

How closely have you tracked accuracy while sending those rounds downrange?

How much rapid fire was involved?

I allow about 5 seconds between shots. I use 5 rounds at a time. The accuracy has gotten steadily worse. I cannot shoot a decent group at 100 yards with it. That was the reason for going to the SMK 120. If it won't shoot a decent group with them I am considering getting a Lilja barrel.
