Hi guys. Ive always made my own Shell and Passed Them so the size was just right to fit smoothly in my mortars. This year ive bought som pre-made Shell(3,4,6”). But they seem to be at bit smaller than my mortars? For example, the 6” has about 15mm of freespace between Shell and mortar. Is this normal or do i make my own Shell a bit to large? My concern is that the Shell wont go High enough. Im from Denmark so here things are in cm. My 6” mortar is 150mm. My 6” Shell might be around 140mm...
