Barrel break-in

Here's one we can chew on for a while.

New barrel break-in;

Is it neccessary?

Does it really do any good?

is it worth the time and expense to do it?

If you do it, what's your recipe?

No. A good barrel won't need it and a bad barrel can't be helped by it.

Barrel break-in

I don't neccesarily "break-in" any barrel in any special way other than just shooting it. I usually shoot a 5 shot group and clean the barrel and let it cool down before shooting another 5.

Ive owned rifles that I didn't break in and rifles that I did. Never found that it does the slightest bit of good. It's just short of rabbits feet and tea leaf reading in my book. The best I can say is it doesnt hurt.

Barrel break-in

I've always been a believer that all barrels are just a bit different.
That the first barrel in a run of manufacture is slightly different than a barrel at the end of a run.
Unless you were able to take the exact same barrel and try it without breaking it in and then break it in, how could you ever know if it made a difference?

I know 3 Marine Corps armorers, 1 current and 2 retired who build/built match and sniper rifles as part of their duties. All 3 are big believers in break in. Granted, the average big game hunter does not need the accuracy of a match grade rifle, however varminters do fall into the league of the sniper. Big game or small, we all would like “one shot, one kill”. Accuracy helps attain that goal.
I suppose time is a big issue, I begin my break-in procedure while I’m doing the rough zero. Because of all the cleaning involved, it takes longer, but I don’t buy new rifles very often, so it’s not like it’s become my life’s work. I try and squeeze as much accuracy out of each arm without spending large amounts of $$. Break-in is something I do that’s inexpensive.

Once break-in is complete, I don’t get carried away with the cleaning process. A partially fouled barrel normally shoots more accurately than a very clean barrel. Only give a thorough cleaning every 25 – 30 rds or so.

I heard and read quite a bit about Rifle Break In or whatever one prefers to call it at any given juncture. Really, I think it is much to do about nothing, no scientific data that I can find that can be documented. I just don't believe it.
Now, saying that, for those that are firm believers in RIFLE BREAK IN, here's the question I have : How do you determine the Break In period is over and anticipate someone will say " when all the rounds are in a 1/2 group". Wrong answer ! That's the shooter, not the firearm Big smile Big smile Big smile

Barrel break-in

I always break in a barrel. I have absolutely no idea if it helps but it doesn't hurt either. My feeling is that it smooths out any of the small imperfections in the rifling. Lapping would do the same thing probably but I am reluctant to use abrasives in a barrel. The rifles have shot better after the break-in but that can have as much to do with me getting used to the new rifle as it does with breaking in the barrel. Allowing the barrel time to cool off between groups and not overheating it is the biggest advantage. Cleaning between groups allows the barrel time to cool off.

I have no problem with that Chester as like I said, it doesn't hurt. But if you want... just to make extra sure.. I know this Voodoo Priestess in New Orleans who can wave her snake and chicken feathers at it. neener!

Bought a new rifle and the manufacturer listed a break-in procedure that I followed.

Does it matter? Dunno, but it doesn't hurt to follow a break in procedure.
