Howdy,
I am using one of Dakota Widowmaker's dies and sizers,and they worrk great! The are perfectly smooth if you crimp over the front driving band. If they are longer, at least in my infantry rifle, you have to jigle it a little. I get about 43 Grains (volume) of triple 7 loading this length. That should more than equal the 45 grains of Musket powder the originals used.
I have not been able to shoot it, However, as the rains have been insessent (14 days out of 17 I have off for school break), with a total accumulation here at my place in excess of 20" OF RAIN! I got a rain gauge on the 4th day of intense rain, and have measured 15 inches just since Chjistmas!)
