barrel break in...

shoot 1, a wet patch, wait a couple of minutes, brush out, another wet patch. wait a couple of minutes, a dry patch

repeat the process 15 times.

Then shoot 3, a wet patch, wait a couple of minutes, brush out, another wet patch. wait a couple of minutes, brush out, another wet patch. wait a couple of minutes, a dry patch

repeat the process 5 times.


Then shoot 5, a wet patch, wait a couple of minutes, brush out, another wet patch. wait a couple of minutes, brush out, another wet patch. wait a couple of minutes, brush out, another wet patch. wait a couple of minutes, a dry patch

repeat the process 3 times...

What I have learned on AR, since 2001:
1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken.
2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps.
3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges.
4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down.
5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine.
6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle.
7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions.
8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA.
9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not.
10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact.
11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores.
12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence.
13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances.

Be patient, it's only for the first 1500 shots. Is this written in stone somewhere.I thought with some shooting and cleaning in the normal sense, it would probably be alright. Two equal barrels shot your way and then shot maybe a little less anal. The people in the gun cleaning industry, probably push for the more anal way. Who knows for sure?
Have fun at any rate.

Guys,

Have never done this before...so I thought I would give it a try. I doubt it matters much.

But I can report it is very boring...

i've done it ...
aint worth the time in a hunting rifle...
you are trying to remove the roughness and "align the grain" (whatever THAT means) .. but cleaning it every shot is counter productive...

shoot five..
1 wet patch
1 dry patch
shoot 5
repeat
shoot 3 for group..
if you HAVE to...

I have done it both ways myself.

I find it results in a much easier to clean barrel by doing a "proper" break in.

Shoot, clean to bare steel ( remove all copper ) this can be painstaking in a rough barrel. Then repeat, the thoery is to "iron" out some of the roughness in a bore. IMHO it seems to work. In a lapped custom barrel I find it makes no difference.

IMO you gotta brush to get the carbon gone before you can use "chemical" to get the copper out.

Mike,

Try dropping those wet patches on your foot & expect a different result?

Man, you are one patient fellow - never broke in a barrel like that and all of mine are really fine shooters because I won't own own a rifle that will not drive tacks.

Obviously I just don't have that "magic" feel; 'cause when I clean mine they all feel smooth, after cleaning that is - I guess I'm using too much JB, so about a gazillion cleanings later they'll all be smooth bores.

shocker

I thought that was still practiced only by the criminally anal. By the time you get it good and broke in, it'll be time to re barrel. Rots of Ruck.

I'm sorry. I can't right now. I'm not done with my barrel break-in.

I did it a few times and gave up. Way too tedious for me. And I then bought several used guns and figured it was pointless in them. That was a few years ago, and I haven't been back since.

Why is it tedious? You shoot, clean, then shoot one of the other 1/2 dozen firearms you brought along. Then repeat.
Hope you're not at a range, that would be REALLY boring.

Get a bore guide, several bronze bore brushes for the specific caliber, some JB bore paste and some kroil. Mix kroil with jb bore paste. Coat bore brush liberally with this mixture. Put 200 to 300 strokes down the barrel. I usually clean/switch bore brushes every 50 or so strokes down the bore between cleaning. Does it work. Don't have a clue. dancing

I can say I've not done barrel break-in in years. I do this on all rifles I purchase, new or used, (and I do purchase a few) and have no problem getting good groups from rifles treated in this fashion.

Yup! I twist a cotton patch tightly around the brush so's it kinda digs in. It helps hold the JB on the surface.

I've done it on a couple of rifles. The bores don't seem to copper foul as badly, and seem to clean easier also. I used the Tubbs bullets on one, and the wheeler method on the other.

When I was shooting high power, I broke in all my target rifle barrels that way. The barrels were long enough to allow for cutting the threads off and rechambering after accuracy at 600 yards began to fall off, generally at 1500-2000 rounds. This would allow for another 2000 rounds of accurate shooting. The best 600 yard scores I ever shot were with a re-chambered barrel.

Cleaning afterwards consisted of running the rod through the barrel with a dry patch, until half the patch protruded from the muzzle, then saturating the patch with bore cleaner and pulling the rod back through the barrel. Ten or twelve repetitions with the wet patch, then ten or twelve more repetitions with a dry patch, and the job was done. Never used a brush.

These were the instructions I got from famous bench rest gunsmith George Fullmer of Oakland, CA, who installed Schneider barrels in all my match rifles until he passed away a number of years ago.

I use a somewhat modified version of this technique with my hunting rifle barrels, which will never be fired nearly as much as my target rifles.
