Conditioning new barrel before break-in.

[muleman69]

Shoot once run a wet patch and few dry patches to clean it out. Shoot two shots, patch it the same way as the first shot. Shoot 5 and repeat step one. Shoot 10 shots now when you run a wet patch through it look for copper. If it's a good barrel you shouldn't see any copper fouling, let her rip you're good to go. I hardly ever scrub a barrel out, maybe every 500-600 rounds. Let the target tell you when something needs to be addressed.

So you can get that many shots before a clean? What about throat carbon and copper? I'm just asking as I'm not crazy about cleaning

I JB
the chamber And the crown end
300 strokes on the chamber and 200 on the crown And 50 or more on the barrel
I never
have any copper problem
The IBS match was won today with a Savage Dasher that was broke in that way
And the barrel has over 3500 rounds
He beat the best
Or who I consider the best
MR Bart

If this poster has won an IBS match that means something.

But if this is recommending 300 stokes with an abrasive in the bore near the chamber and 200 more strokes near the crown end, I want to caution readers strongly against this. Based on my experience and conversations with top match barrel makers this recommendation is extremely unwise.

To be truthful, I considered the advice sufficiently inappropriate that I contemplated deleting this thread altogether.

Most good match barrels are hand lapped. Aggressive use of abrasives for 200 strokes in the outboard end of the barrel could alter the dimensions in negative ways.

Honestly I consider the recommendation extremely unsound and should NOT be done with most barrels.

Use a conservative break-in method. See how the barrel shoots. If it shows fine accuracy, do not do anything that will change the barrel's internal dimensions.

That is way, way over-pressure, very dangerous. Draw your own conclusions as to whether anything savagedasher posted was to be believed.
