Cayugag,
Glad to hear BM3 is working for you. Based on my experience with it, I'm surprized you can load that many shots without swabbing. I've tried it in 2 different guns and quite honestly, I'm not impressed. I've tried it with bullets from the 460NE down to the 250SW. The larger conicals were very inconsistant, like 8 to 12 inch groups at 25 yards. The lighter bullets worked better but not as well as 777. When shooting the Shockwaves I could only load about 3 to 5 before having trouble seating the bullet, almost as bad as a 777 crud ring. On both rifles after shooting a round or two, I could see white streaks at various places in the bore where the fouling was adhearing to the bore. I may try what I have left in one of my round ball guns but I don't expect to be using it in my inlines any time soon. I found it about the same as 777 when cleaning the rifle also.
