Michael. Is it possible that such large touchhole due to corrosion? I'm afraid that with such a large touchhole at such small caliber will be very low compression. It seems that diameter of touchhole is about 6-7 mm (by the way is this hole canycal or not? what is the diameter of hole at top and bottom?)
