Went to my Dad's shop to get a torch tip cleaner. Checked the flash hole size. 0.028 wire fits in but the file part(.030) didn't. The tip cleaners have about 1/2" of wire before the file part of the wire starts. I measured the wire with calipers at .028 and the file part at .030. The next wire was .032. I just got to get to the range now and report back.
Thanks everyone.
