ctafoya Report post Posted November 16, 2014 So we took my wife's new Remington 700 7mm out yesterday and "broke" it in. The results are the same as my savage 116 300wsm that saw 50 rounds before it ever had a patch run through it. Both are .25 or better at 200 yards. Is break in just a myth or did I just get lucky with my savage? Share this post Link to post Share on other sites
vinniebeeks Report post Posted November 16, 2014 i could tell a difference in my tikka 7mm mag. id have 2 rounds almost touching and a third off about an inch or so. cleaned the barrel and i can have 5 rounds touching. i run a bore snack threw it every 5 rounds.

308Nut Report post Posted November 16, 2014 Every barrel is unique. Breaking barrels in means different things to different shooters. When I 'break in' a barrel, I'm just trying to burnish the metal. I'm not trying to 'smooth' anything out. 1 Share this post Link to post Share on other sites
rcdinaz Report post Posted November 16, 2014 I tend to agree that for a very good barrel it probably doesn't matter much. I certainly haven't seen much in the way of differences. I have done full break-in cleaning after every shot through the first ten, then after every five, etc. This was on my two custom guns as it was recommended and for the money I was not going to skip it. This last custom barrel in 6.5 I was in a time crunch so I just shot it when I could and cleaned it after the first box. It shoots great... I am not convinced there is any real science over the long term, maybe there is. Now for something like the Tubbs System there seems to be a lot of reasons the system works for a barrel not already shooting very well.. 1 Share this post Link to post Share on other sites
lancetkenyon Report post Posted November 16, 2014 Here is my very rigorous break-in procedure with every new gun: 1. Clean barrel from factory. 2. Bore sight and sight in with a group of three. 3. Adjust crosshairs as needed and shoot a group of three. 4. Shoot one 5. Shoot one 6. Shoot one 7. See number 4 through 6 and repeat. 8. When groups start to open up, or if gun will be stored for more than 6-9 months without getting shot, clean. Seriously, I have guns that go between 50-800 rounds without cleaning the barrel. If it ain't broke, don't fix it. A clean bore is far more inaccurate than a cold bore. 1 Share this post Link to post Share on other sites
PRDATR Report post Posted November 16, 2014 I won't say that's the norm for the Savage or the Remington. On the contrary .25 is unheard of at 100 yards with a factory barrel. The exception were the old Sako's in 6mm PPC and the XP-100 in 7BR so you're doing ok. I know that most rifles are test fired before they leave the factory but Tikka does not clean the rifle before they ship them out. I don't go Willy Nilly with a new rifle but shooting a box of shells to sight it in without cleaning it won't make a difference considering that manufacturing just keeps getting better and better.

10Turkeys Report post Posted November 18, 2014 Honestly I couldn't say that barrel break in helps in accuracy, but what I have found it sure makes the barrel easier to clean for the life of the barrel afterwards. By the way most of the barrel manufactures have a break in procedure on their website, so they must think its a good idea. Share this post Link to post Share on other sites
