using .22 cases as a cap substitute? Pulled the heads and powder for Aquila Calibris and they do fire on the nipple. I took a rod with a clean patch on a screw barrel took off the barrel and put the patch on the rod and placed it in the powder chamber. Apparently due to contaminants and burn marks on the cloth some heat makes it to the chamber. I know its not economical but it will work in a pinch. Anyones thoughts?
