I'm not sure this will help, but I measured two seperate 12ga. frames sleeved to 45-70 at the muzzle. One center to center was 1.025 and the other was 1. I checked a similar 12 still a shotgun and it was about .090 Neither rifle crosses at 100yd. but we had to spread the bbls.
Could you messure it on the breech also to see how much the are pointing together?
