Barrel Conditioning "Wow"

I have always spent a lot of time breaking in a new barrel because who can argue with the logic of it. I have a whole new respect for the process now!

I was breaking in a Howa .223 Sporter this weekend which had just finished curing (three weeks) the duracoat camo job I had shot it with.

I shot out the center target sighting in at 100 yards and and j&b paste every 3 or 4 rounds followed by a wash out with wd40 a swab out with tight patches with clp and dry patches. I'm up to about 40 rounds at this point.

I shoot the number 1 corner target with a group of 5 that looked real tight except for my fouling round. I then really scrubbed the hell out of the barrel until I got no color with j&b, sweets and followup with the wd40 and clip.

My third and fourth group were noticeably tighter which I thought was remarkable since I was only about half done.

When I checked my targets I was amazed, the first forty shots were 90% perfect keyholes!!

There was not a single keyhole in my third and fourth target. Each was around 3/4 inch groups.
The only thing I could figure is something was left over in the rifling that was stopping/slowing down the bullet rotation. My grandpa would have said I knocked a dirt dobber nest out of it, but there sure was something in there.

I think this rifle will be a real shooter after another round.

Data: Hornady VMax 40 gr. 28.8 gr. Wc846 BC .200 SD .114
Probably somewhere north of 3400 FPS. Winds 10-15 gusty right to left crosswinds.
84 degree F 90% humidity.

Re: Barrel Conditioning "Wow"

For corn cob factory barrels, perhaps correct. For quality barrels that have already been hand lapped, you have more risk of doing damage in my opinion.

The only part of a match barrel which might have some issues might be the throat, due to the chambering operation. Cleaning the throat is not the same job as scrubbing the full length of the rifling.

Don't think more "breaking in" is going to make that load shoot any better or even the gun for that matter.

"That load" has been a tack driver in my Howa Varmint with the same 1 in 12 twist for years. I respectfully disagree!

I have Howas , Remington 700`s, and Savage short actions and long actions in my arsenal.
Howas are my favorite for repeatability. But like my kids I love them all!

What does corn cob barrel mean. Is that what the posh people call what the common man can afford? If it is I'm proud I am what I am.

I wouldn't trade my shooting skills and experience for all of your $1500 barrels and cucumber sandwiches between rounds.

IMHO
