Looking for a quality barrel guy

I have an Ataman M2 .25 caliber rifle, and am looking for someone that can duplicate my barrel with a Lothar Walther polygonal non choked barrel in same caliber to shoot slugs. I haven't been able to find anyone out there that can do it (as of yet) but have been given the name and number of guy (Alan Zasadny) that can, but have no way of getting a hold of him. Any help would be appreciated, thank you very much! By the way, it is a .250 diameter barrel.
 
scooter you have a dimension wrong

25 caliber is .250" and you say .250" is the diameter of your barrel ?

you might re-measure the outside diameter of your barrel
