Hey, yeahbub, thanks for the input!! You have posted exactly the 'secret method' I have used with some success: patches must be however long they must be to produce however many 'wraps' to actually work. It's all trial and error (my Post #4). Happy to have confirmation that .30's can be 8mms as noted in my Post #6. It'll be literally months before we here get to actually shoot this '.338' lot. Anyone?? Bueller?
