Dono,

That wax idea of yours should work great! A lot less redneck than the "touch of white glue" crimp haha.

Daryl,

You could certainly be correct on the ball weight. All I know is they weigh less than the copper slugs when I weigh them out side by side. These days I am using old lead sheeting (originally used as sound insulation) with a bit of silver solder mixed in. It isn't an exact metalurgical science at this point, but it's the best I can do.

Regarding your black powder load, do you think it is possible that pure black powder is less "dense" than the pyrdodex, and that is why you can fit 191 grains into your hull? The most I could fit inside a 2 3/4 hull (federal) was around 150gr, with a fiber wad and the ball sitting on top of that, with the glue crimp. I'm not doubting you, (like you said, just an observation) but I suppose the best thing I can do is track down some 2f black and see how the two powders compare.
