regarding regulation of sxs shotguns.... old ed has done some sleeving in the past as well. i had him sleeve a parker dhe a few years ago. he asked me how i wanted it regulated? i answered, what do you mean? his response was, at what distance do you want the shot patterns to converge. my response was what do you mean? he sighed and looked up at the sky and then back at me and responded: usually when i sleeve a gun, i regulate the new barrels to converge the shot patterns at 40 yards. my response: sounds ok to me! anyway, he sleeved the gun and the new owner patterned it at 40 yards. guess what, it shoots to point aim with both patterns one on top of the other at 40 yards....

keep it simple and keep it safe...
