I can deal with loose fouling, but hard carbon is a whole different issue.What’s the best solvent to clean a barrel after shooting loads with Varget?
Geeze it’s dirty powder.
Ok. Where do you get this stuff from?Carb Out worked well for me with a bronze brush.
Try N140 in your next one.
^^^^ This.Hard carbon won't dissolve in with any solution currently available. Requires an abrasive and elbow grease. Just because you get a clean patch doesn't mean the hard carbon is gone.
How do you know? Clean patches, visual inspection or a borescope?Have shot Varget for decades and never found it to be overly dirty. I use Butch's Bore Shine and a bronze brush and it gets clean every time.
Again, how do you know you won't have a problem the next time you go shoot?Never had that issue - but I do clean the FTR rifle after every shoot. I use Boretech Eliminator and have done since it came to the market, pleased to find a cleaner without ammonia.

What's your bore look like after that? Any etching?Baked hard carbon can easily be softened with "Piston Kleen"
then cleaned the normal way. I slop it in there with a bore mop
and let it sit a few hours. You'll push out black sludge.
I guess you and I are in the minority because I've shot Varget for so many years that I can't remember how long in the 223, 22 250, 243, and 308 and never had an issue with performance on target. It's one of the most accurate powders in those calibers collectively that I've ever shot. I typically clean every 30 to 60 rounds depending on the caliber and rifle barrel.Have shot Varget for decades and never found it to be overly dirty.

Just because you haven't had a problem doesn't mean you can't.
