I use Canadian Tire fuel injector cleaner on patches for the heavy lifting followed by kroil. It takes 20-30 shots for the bores to settle down after the cleaning, no doubt laying down lube on the bare bore. Call it one shot per inch of barrel.
My sporters get cleaned occasionally.  |
With cast bullets and smokeless powder I use to use Canadian tire carburetor cleaner.
