OK , it\'s not a total pooch screw , the pre drill for both threads is same size so I have 100% thread integrity so the part is technically good but the different thread count means 1 special threaded barrel to match my mistake and I\'m not cool with that , so for punishment for not looking at my tap before I used it I\'m gonna carve my new part out of an oversize slug to keep me busy until I head home to see family
