That's a first class Barrel. Good before cleaning, excellent after cleaning. I clean after every shooting, oil the barrel, deoil before the next shooting. So I have every time the same start ( especially for hunting). I had corrosion in several barrels before I changed my system. I use paper tissues on a woolbrush for deoiling ( cheap & good).

Bought a 22 hornet unseen. Once home, i saw it had pitting with my bare eyes - about half way in and close to the muzzle. The rifle was in good condition, but i guess they had forgotten to remove snow from the barrel after hunting ripor. I went to a friend with a borescope and verified this. We decided to remove 5cm of the barrel and re-crown. Said and done. I cleaned the rifle really well with thorroclean (excelent product). I started loading some cartridges and over a period of perhaps 100 shots the rifle started grouping really well. I can still feel the pitting when cleaning, but I have settled on ignoring it as the rifle shoots 15mm or better with proper ammuntion. Anything around a MOA is great, as the distances i use a hornet for is modest - its a .22 caliber rifle with modest velocities after all. bought a 222 with similar issues, but i never recrowned it. I just plastic bedded the stock and cleaned it well but the first 50ish shots spread over a entire a4 paper. But after a couple sessions on the range, it shrank the groups alot and started to shoot like a 222 is expected to. It went from shooting 52 grain FB over entire target (45cm?) to almost single hole. sometimes rifles are not kept well, and cleaning and some patience is needed.. I imagine the cleaning and following filling with new copper made the rifle calmer. I try and not clean it excessively now, just a couple patches thorroclean every 50-100 shot.
Hello my Nordic friend. Great video. Bore scopes can be a very useful tool. But often they cause us to take un needed actions. Many rifles shoot very well, but their owners look at the bore for the first time with a bore scope and go crazy. One must be careful to not remove all of the seasoning that contributes to fine accuracy. I posted a couple of videos talking about over cleaning. I have come to the conclusion to shoot until your accuracy begins to fall off. Then clean with as mild of a cleaner as you can that will restore your accuracy. Certainly there are rifles that can benefit from the super cleaners but I have seen more accurate rifles loose their accuracy from these cleaners than any other cause. So if you have nothing to loose try them. But if your rifle is shooting just fine then why take the chance. Again thank you for a very informative video. Good luck hunting this season and video your hunts. I love watching them. Dennis
Thanks for your comment Dennis! Yes, I completely agree regarding degree of cleaning necessary once the rifle is shooting at a steady level. I just want to "thorroclean" it to show the difference between "dirty" and very clean bore. Take care 🙂
@@dennispritchardoutdoors7882 Nope, no time for that kind of stuff 😓 In the past when I used to shoot a lot at 300 meters I made some notes on where the CCBS (Clean Cold Bore Shot) hit compared to the following shots. Other than that I have not made any great investigations into this field.
