Probably discussed before, but I couldn't find it. Last weekend was nice here for the first time in months (under 100 degrees), took the son out to the range with a 1000 rounds. Had planned to shoot a couple hundred, but was so nice out we stayed most of the afternoon and shot over 500. I have a 6920 and got to thinking how long the barrel on these will last? 10,000, 20,000, more? I'm past the 5,000 mark.
