The guy in the video has a break in procedure similar to mine. My last break in was a 30rd mag bump fired.

Nice. Very entertaining...
I have doubts myself as how much "proper" break-in will affect accuracy. My (of all things) Del-Ton M4 has shot <1MOA groups since day 1 till now 500 rounds later with no set "break-in" On the other hand, just got a Savage bolt action and was shown what happens if I run a bore snake through the barrel after each round. After each round, ran a clean bore snake with some CLP through and then took a strong magnet to the snake. Every time for the first 20 or so round, saw visible amounts of metal burring come off the snake onto the magnet. One would think that if not for the proper break-in, those naked eye visible fragments would've ground themselves into the bore and did some damage... I remain a novice though to the break-in tradition... |

The shooter's lack of eye protection clearly proves he is an expert in all matters concerning proper firearm handling. I guess someone believes in breaking in a barrel  Actually, I believe it might help and it damn sure can't hurt. I believe the same thing about new engines. I wouldn't be inclined to repeatedly red-line a new motor although drag racers probably do it all the time. It's your barrel. If you feel that break-in is a waste of time- do your thing. |

If the rifle he's shooting is brand new and unfired, extra caution would probably be worthwhile. Maybe I'm overly cautious. I always wear eye protection when shooting. |

Is that really how you're supposed to pronounce Noveske? I've always pronounced it no-visk. I didn't know it was pronounced no-ves-kee.
Getting back to the topic at hand, I've said it before and I'll say it again: barrels do require a break in period before they shoot their best, but there is no special ritual you have to go through to break it in. Just shoot it like normal and it will break in on its own. |
| Barrel break-in varies, or at least it should in theory. Chrome-lined barrels really should not need a break-in, the chrome plating is way harder than the bullet jacket, and trying to "shoot-and-clean" is not going to have any real effect on it. Besides, most manufacturers have already done a ten round rapid test on the weapon anyway. Also, chrome-lined barrels are not technically made for sub-groups anyway, they are made to last under rapid-fire and high-heat conditions. Now a CM, stainless, or non-hard chromed barrel is a different story, the barrel should be broken in using some type of shoot-and-clean procedure. This basically "fire-laps" the barrel, knocking down any microscopic burrs and removing any manufacturing debris that might be left in the barrel, and usually CAN result in a more accurate and longer-lasting barrel. As the previous post, you will get gunk, microscopic chips, and smooth any manufacturing deformities by doing this. Also, on Chrome-moly and stainless barrels you can use "copper cleaner" during your shoot and clean, it works best. But with "chrome-lined barrels, DO NOT use copper cleaner on these as the chrome-lining process involves a "copper-nickle-chrome" plating process, and it has been shown that any microscopic pores in the plating can cause the copper cleaner/remover to migrate and attack the underlying copper plating, causing premature damage to the chrome plating. |
