Using my new "unloader" internal bore gauge I got the following

Left Bore - .735 Right Bore = .735

Left Choke .723 (.12) Right Choke .727 (.8)


I got lucky and assume right and my Mic is closer than expected.... Just happy the measurements are in line with what other members have reported on in 12ga PR and weren't opened up..
