I shoot Damascus barreled Lefevers on a regular basis. All those I shoot from a lowly H in twist to my "go to" sporting clays A 16 gauge have been examined and measured by those who are better at doing that than me. Reloading is way too hard to do in Hawaii so I use RST, Polywad and New Era low pressure ammo. I don't get to do a lot of hunting, so when I do shoot its 25-100 rounds at a time at the trap or sporting clays range. No problem so far.
I have yet to see a problem at the few side by side meets I do get to go to with those shooting good condition Damascus guns using commercial low pressure ammo.
On the other hand, I have seen a number of blown barrels, both Damascus and fluid steel. However, I rarely got the details of what was being shot and the circumstances behind the incident that caused that barrel to blow. I quit hunting public lands in New York after I saw a guy using a loaded gun as a crutch coming up out of a ravine and then attempting to blow the dirt out of the end of the barrel while the gun was still loaded. He then proceeded to resume hunting without even checking the barrel.
