Hey Daryl.
I doubt that it would have made much of a difference but The load chain is the slug with TC wonder lube, felt wad, 80gr of 777 (this time). May change the lube to beeswax, Crisco, olive oil as it would probably be less of a mess if I pan lube.
May have to put another thin wad between the slug and the felt as I get the occasional flyer and it may not be detaching consistently.

What really impressed me was the pistol which takes 50grfff behind a .570 ball. Accurate enough and clocks around 850. Not surprisingly it went right through.

Tom
