[QUOTE="reubenski, post: 1541338, member: 36515"] I've run 45gr of 4831SC in two 243 barrels. 46gr SHOULD not be too hot in an AI. That said Ive seen as much as 120fps variation between jugs of 4831SC. Regardless 46gr obviously isn't going to work for you. Frankly, it does sound like a carbon ring. I would look around for a bore scope so you can see it and understand what it looks like. I recommend CLR. Carbon rings can be extremely stbborn and the amount of brushing required with a more mild solvent makes me pause. Not sure I'd eawa to subject my barrel to that. Use an aggressive solvent and keep a soaked patch in the throat with a jag for 20 mins or more at a time. Brush with a bronze brush. Patch out and use the borescope to monitor progress. Good luck [/QUOTE]
