6 Dasher No-Barrel-Cleaning Test

Hey Carl, any update on the barrel? You by chance the same Carl as W150 in the WPR?
 
Carl,
Really appreciate your willingness to share your findings.
Clearly a lot of time spent documenting, then adding the extra layer of posting… generous.

I’d like to believe that conceptually the outcomes could apply to my 6ARC.
Any speculation on how an alternate powder might affect the stability shown thru the first 1300 rounds?
i.e. Are some powders inherently more likely to accumulate crud, carbon rings, whatever…. that would negatively impact the exhibited outcome thus far?
I’m thinking of 8208 XBR, or say LEVERevolution.

Glad it’s appreciated.

The 6 ARC has less capacity vs bore diameter than the Dasher, so everything should be milder.

Speculating here, but I’d expect 8208 would behave reasonably similarly to Varget. Lever clearly has velocity potential in many smaller capacity rounds but I don’t have enough experience with it to give an informed opinion.
 
Just want to add that I also very much appreciate you doing this. Seems like when we're demanding the precision that we do for PRS, then things get a little more odd. I switched to suppressed only about a year ago, and have a buddy that did a couple years ago, and he was a non-cleaner when shooting with brakes, and now is adamant that you are going to have to clean at some point with a can. My current PRS barrel opens up from a .15-.2mil gun to a .45-.6 mil gun at around the 450 round mark it seems. A good scrubbing brings it right back, the first 3-5 rounds are usually around .3-4, and the next 10 are usually .25 at the most. On the other hand, my NRL rifle, always suppressed, has never ever been cleaned, and with around 1700 rounds on it will still put 10 rounds into a .2mil cone consistently. So if people wonder why there's so many mixed opinions on cleaning...😂

Agreed on the sentiment. I have been doing my best from the start to try to avoid bias and just see what happens. I have had my own barrels that have responded positively to cleaning, regardless of how this concludes I won’t be trashing the cleaning products I do have anytime soon.
 
I am interested in this project because I shoot competition weekly and clean far less than anyone I know but I seem to see a drastic difference in accuracy at about the 400-450 round mark across the 223, 6.5 CM and 6BR.
This also seems to coincide with elevated pressure.
I don’t use brushes, just a couple of patches with JB on a tight patch, and it takes about 10 rounds after to really settle down again.

When I do clean, I use a foaming bore cleaner and patch it out, usually three rounds of foam and 7 or 8 patches is all I do. That's been my program for the last decade, till I started experimenting with not cleaning at all. This isn't my first barrel I've tried not cleaning on, but it is the first one I've gone to these lengths to control variables.

Any observations on powders that impact the need for cleaning, more or less?

I shot 90%+ Hodgdon Extreme powders or XBR (which I believe is very similar) so I don't really have experience with other types of powders for comparison.
