I've been reading the threads about 777 and crud in the breech. It was said that if you switch to fffg 777 you will get less crud buildup. Awhile ago I read somewhere that people who shoot powerbelts got bad results with fffg 777 versus good results with ffg 777. Does anyone have any knowledge of the performance of powerbelts with fffg 777? I can't remember where I read about this. I get crud in the breech with ffg 777. The bore seems fine though. Also, does anyone have any advice about field cleaning the breech area? With a cleaning jag you can't rotate the rod with a patch so what is the best way to scrub the bottom of the bore? I'm talking the actual back of the breech, not the side where it's rifled.
