I don't understand why any barrel maker uses a 1-10 today.
New Norma 17 remington brass.What are you using for brass? -Al
Once again...you may want to try the Dyna Bore Coat. It's not magic but it does help most factory-ish barrels. Then again, even if DBC doubled your round count before cleaning was needed, that may still not be where you want it to be.Contacted Shaw about the barrel and they said that fouling inside of 20 shots is just the 17 remington and there is nothing that can be done to improve it. They recommend cleaning every 20 rounds at most. I asked about lapping the barrel and they said it would void the warranty (which there is not a warranty as I bought it used) and it would not improve anyway. I do not believe that 15 accurate rounds is the best I can hope for with this cartridge as others are saying they are getting accuracy for longer strings with better barrels. I am seriously considering doing the 1000 stroke JB patch or may just send the barrel packing. Maybe this is just not the caliber for me and I will stick to my 17 hornet if I want to shoot .172 bullets.
