So I have been shooting rifles for 30 years, and clean them after any trips to a range, or maybe once a season for just hunting, but I have never done anything like the following that I came across on the internet:
"Most hunting rifle barrels have not been properly broken in, which helps to minimize accuracy-reducing fouling. If not properly broken in, we have observed hunting rifles to completely foul out in as little as five rounds. Many will foul out at fewer than 20 rounds. When a barrel fouls out, accuracy is dramatically reduced. Properly breaking in a rifle barrel is a must for our target rifles and our hunting rifles. We believe that this step is very important to optimize the accuracy potential of your hunting rifle. You will not have to worry about your rifle fouling out during the hunting season.
The break-in process is simple but takes time at the range. Use any inexpensive ammo that you can find. Start with a clean barrel, fire one shot, and clean the barrel. Make sure that you get all the copper out. Repeat the single shot/clean routine for five shots. Next, fire two shots and clean. Repeat three times. Now, fire three shots and clean. Repeat three times. Cleaning the barrel should become easier and copper fouling should be minimal."

I just bought a Cooper, easily the nicest rifle I have ever owned, so I do want to treat her right. It is NIB, but of course they have the three shot group card from the bench showing its sub 1/2" MOA. So it has been fired at least three times already, and is (or was) obviously very accurate.
Should I be doing the break in described above when I take her to the range for the first time to sight in, or should I just go shoot and then clean when I get home?
Thanks in advance
