Reduced Fouling: Fact or Fiction?

[longrangehunter]

Canted Land Rifling: 5C, Obermeyer 5R, Polygonal, Ratchet, etc. The newest latest and greatest, or just hype?

So my point to this article is if these new types of rifling are suppose to reduce fouling, then why is this barrel I'm trying to clean "The dirtiest I've ever seen in a custom barrel". This is the longest cleaning process I've ever witnessed in the last 20 years, I've had factory barrels clean up better! Even the Kimber barrel was easier to clean.

I've had to soak the barrel in CR-10, Montana Extreme, push miles of patches w/ JB bore cleaner..... what the heck, I'll never get any load development done. Should I go back to Bow Hunting?

This is not what I signed up for? What have you guys found w/breaking in these new barrels, and afterwards?

My Hart barrel on my 280 AI cleans up in a snap of the fingers. I have never used any of the barrels you mentioned.

Thru the years, I've had barrels that were the worst, dirteist, terrible looking inside I ever owned. But did they ever shoot well, even after 100 rounds or so. And changing powders did help in some cases. Even different primers made a difference in cleanlyness. The worst of all was an old Ruger #1V in 22/250. But after a 100 shots in a p'dog town, it would still group into 1.5" @ 300 yards, but the barrel looked like a gravel-road inside. So I'd put it to soakin' with Hoppee's Copper cleaner and shot the 22/250 Remington for about an hour, with the same loads, and it looked as though it had never been fired.

These days I find that Shooter's Choice bore cleaner is pretty darn good stuff. I cut my patches to snugly-fit the bore,push a wet patch thru and let the rifle set (level/horizontly) for awhile. Then bronze-brush it four passes then patch it again. In most cases, its clean. I even tried using the electrric-rod system to see if it found anything .... nothing.

This is not an endorsement of any product, just what I find that works, YMMV.

Yes, somethings are just that way. This Shilen Ratchet 4 groove barrel Kimber Montana 6.5/300 WSM has gone thru 300 patches in the first six (6) rounds. It is just starting to maybe slow down? But it does seem promising?
The owner of Shilen Rifles is not a big fan of super cleaning his guns anyways, maybe rightfully so?

Here's is the first three groups after I had them recut the chamber.

I've got a few Broughton 5C barrels. They all clean easily but I can't say that it's the canted rifling that makes them easy to clean. I buy them because they shoot extremely well.

Supposedly, the canted rifling barrels shoots faster and clean easier than barrels with conventional rifling. It sounds like you may have an exception to the rule.
