You would think you wouldn't need to break in a custom barrel, but my Trueflite Ultramatch in 7mm mag copper fouled like crazy from new. It eventually settled down after a few hundred shots down it.
At the start it took 24hrs of regular patching and soaking overnight with Boretech Eliminator to remove the copper from one shot.


To be fair I only brought the Truflight as no one else had a .375 barrel when I needed one.

i was told by a decent gunsmith, that breaking a barrel in, was essentially just smoothing the rough spots off the edges of the rifling lands, to help settle the barrel in..

my 2c worth..  Shocked


This is essentially correct. Another term used is burnishing. Fire, clean, fire, clean. The bullet is smoothing things off, in laymen terms.
I once bought a Rem Model 7 that had been shot a lot but I doubt had been cleaned properly from new as it was a copper mine. Took ages to clean out and I basically had to start from scratch as if new to slow the copper fouling down.


Yeah, I've got a second hand gun here that was re-barreled 1961 in Germany. I've had it probably forty years and while the rifling is still sharp and clean, and it's accurate enough, it has always been something of a bugger to clean.
Have put a few rounds through it too - just never seems to have smoothed out which has had me wondering the previous owner's cleaning regime.
I'm fairly anal about cleaning - comes from shooting black powder I suppose.

The only way you can hurt a barrel when cleaning it is to rub the bore , or more usually the chamber/ throat area with the cleaning rod , especially those horrid soft brass or alloy take down rods , or sometimes but less likely, by using certain bore cleaners like shooters choice and sweets one after the other, that combination leaves a deposit that is almost impossible to remove .

When you cleaning, make sure (NOT) to follow these instructions:

Grin Grin

Jokes aside, when I asked Grant from Trueflite this questions here is what he replied:

"You can do no harm by shoot one, clean, shoot 2, clean, shoot three, and clean.... then shoot a group and see how she goes.... if its accurate and does not copper foul, then all good....if you get some copper fouling then clean and polish bore using JB's bore brite or similar...."

I did it like he said and all good. Regular careful cleaning cannot harm the bore if you are using good tools. I got carbon cleaning rod which has a bearing inside the handle and that works really good. Would never touch cheap fold-down rods!

That's worth knowing - will try it on my German.

That too - though I never used either of those.

As for rods, I've got one piece stainless range rods - not too portable though, so for the hills I use a woven wire pull through to pull out moisture and crud.
Did that to my brother in law's gun after some heavy rain whilst still in the bush and pulled rust.

"Where the hell that come from ?"

Have never forgot him saying that.

Water will get in there whether it's taped or not.

Wipe Out bore foam. No scrubbing needed

Have done the break in procedure on plenty of rifles in the past but no longer bother.

Currently, my most accurate rifles are a Sako 85 .308 and a Tikka T3X light 6.5 Creedmoor and no break in procedure was used with either. Copper fouling is minimal in both.

Still, it can't hurt if you can be bothered to do it.

Been a while but a bit of an update,
Went through the Bergara break in process with some Hornady Superformance 129gr, sighted it in at the same time, got groups down to 1.3inches which is ok. Took rifle out to cull some goats a couple of weeks later and used some Hornady american whitetail which I think(and felt) like it shot better, (Im guessing because a little less hot than the superformance), everything landed where I was aiming which was pleasing. Couple photos attached hope they work.

Mine loves the Hornady Precision Hunter Ammo which uses the 143gr ELD-X projectile. Used a box to break her in (clean, shot, clean, shot, clean, 2x shot, clean, 3x shot, clean, 5x shot, clean 5x shot, clean), zero on 100m and to give me some brass to start reloading.

Hornady Precision Hunter Ammo 3-shot group @ 100m after 20 shots:


Reloaded 4-shot group @ 100m:


Make sure you give the Hornady Precision Hunter Ammo a go as well. No need to reload for precision really but only for price...


Cheers,
JaSa

Read the istruction manual that comes with guaranteed MOA rifles. You wont find instructions saying fire 1, clean, fire 1,clean...
Having said that, going thru that process does no harm and gives you peace of mind you have covered all bases.
I love the common sense approach of this guy and all of his vids.

Dragged out my Sako and Kimber manual and there's nothing.  I would have thought if it was so damn important it would be in there.

Whew, sorry mate, I just plain gave up on that guy. My attention span as I have got older is not so tolerant, mmm adaptable. Thought his next one on solvents would be good but gave up on that too.  An hour and 11 minutes odd??
