I have heard many different opinions about breaking in barrels.The problem is many of the techniques I have heard are complete opposites. I was taught that when you have a new barrel there are deficiencies in the barrel and to make the barrel smooth you need to fill those deficiencies with brass. The way you do that is by firing your gun then cleaning starting with a small amount of rounds fired before cleaning and gradually increasing the amount of rounds fired before cleaning. I was taught not to use Sweets or any solvents that breaks down brass. I have heard out of the factory most guns have around 50 or so rounds put through them just to make sure the gun works, so there is no need to break the gun in. I heard the other day that you must run Sweets through your gun to break the brass down because the brass builds up unevenly in your barrel. Now I do my fair share of shooting but I do not have enough experience to say that one way works best. Does any one have some advice? Thanks, Tyler
 
Re: Breaking in a Barrel

The "search" function is your friend!!

This topic has been beat to death on here & every other forum I have been on.

Myself, I say clean well prior to shooting it for the first time and then shoot the hell out of it!!

That explanation is a bit too scientific and long-winded for me......
But I fully agree.

By brass do you mean copper? Sweets will not hurt the barrel. I don't think it is feasable for a gun company to put 50 rounds through every gun. My guess is less than one small magazine for the guns that actually get test fired. Think of that poor SOB that would need to fire 50 rounds through hundreds if not thousands of guns a day!

Don't waste your time doing barrel break-in.

Re: Breaking in a Barrel

I used Sweets and butchs bore solvent, after a long internet search, the method I like the best was the one recommended by Speedy Gonzales, Gap has an article posted on barrel break-in as do several barrel manufacturers. There has been a lot of data on barrel break-in, that suggests it doesn't do much, but why not.
just my two cents
 
Re: Breaking in a Barrel

Just shoot it. Barrel break in is a bunch of bs. A bullet going down the barrel a 3000fps can't be beat for breaking it in and smoothing out the tool marks. Of course, a lapped barrel makes the break in period much shorter. There is no magical barrel break-in procedure that will make it shoot better for longer. In fact, some would argue that over-cleaning is a bigger problem than cleaning too infrequently. It may make you feel better to know that there is no copper in the bore. The $64 question is whether the rifle actually shoots better with a super-clean barrel. The fact that you have to shoot fouling shots and wait for a clean barrel to settle down would suggest otherwise.
 
Re: Breaking in a Barrel

Ive done searches over the internet on this subject... Im by far probably the most junior shooter on this site and have asked around.. Recently I spoke with 2 shooters that I respect. 1 said that you should break the barrel in using the 3rds and clean x3, then 5rds and clean x3, then 10 rds and clean x3. Now this is just one of many break in methods Ive found.. The 1 shooter that told me to do the break in also said that every time you fire a weapon it should be cleaned (I clean mine every single time I shoot them). The 2nd shooter basically said no break in, just shoot it. He also says not to clean a weapon except every 1000rds or so... Ive heard this topic debated to death.. Im going to stick to proper barrel break in and cleaning everytime...
 
Re: Breaking in a Barrel

The funny thing about this subject besides the fact that barrel cleaning is BS is that for those that support barrel cleaning, there is no consistent technique to doing it. It's always "fire x number of times and clean, fire x number of times and clean again" and the "x" is always a different number. Then it's always for a different amount of rounds, is it 10, 20, 33? The inconsistency is laughable.

Sweets 7.62 has Amonia. It will hurt the barrel if left in to long and not cleaning it thoroughly afterward. So says my chemical engineer buddy thats also a shooter.. He said it crystalizes carbon steel. ...SmokeRolls
 
Re: Breaking in a Barrel

Just shoot the thing..Clean it ever so often..I'll try to quote what Lowlight posted once, if I miss-quote this sorry, I'm going by memory.
He had two identicl brand new TRG -42's in 308 to test the theory "cleaning verses not cleaning test".He thoroughly cleaned one of them religously and the other he just shot the piss out of it and cleaned it ever-so often.. He said that the one rarely cleaned shot better and is still going strong after thousands of rounds. He said a person can spend a crap load of time cleaning and not shooting when you could be using that time to shoot... Lowlight: If I messed that up, sorry..I tried.......SmokeRolls
