I am shooting about 50-75 338 Lapua rounds every week and at 1500 rounds that comes out to about 7 months of shooting. People that place well in competitions have to shoot more than 75 per week. Figure, they have to shoot 200 or so a week maybe more. Those of you that really do well in competitions, you must be getting a new barrel every other month. My next barrel will be due in September if I keep this pace. Pac Nor took 20 weeks to get the barrel I have now. Is it common practice to get three or four barrels at a time?
