Any way to identify custom barrel manufacturer?

[rodauto]

A few weeks ago I purchased a used custom 6mm PPC rifle, don't know much about it except that it is very accurate and was purchased from Epps. I am trying to find out what barrel is on the gun. It is a heavy stainless fluted barrel.
Is there any way to tell the difference between button rifled, cut rifled, etc? Can't find a manufacturers name on the barrel.
Barrel starts at 1.215 and finishes at .935. and is 22 1/4 " long.
I think barrel dimensions are pretty standard amongst all custom barrel manufacturers but gave dimensions just in case it may narrow down the possibilities?

Without any makers identification or testimony from either the previous owner or the individual who worked on it, there is no way to tell who made the barrel or when. Unless the twist rate accelerates from breech to muzzle, you are SOL.

nope, but are there any markings on the barrel such as initials? It will at least tell you who built it and maybe they can help.

Thanks Blastattack and paperslayer,
I can't find anything on the gun other than the Name of the action maker.will be posting pictures once I get the permission for posting. Tried using photo bucket but would rather post pictures direct.
I have emailed Epps in the hopes that the seller may give me some information. The barrel is 1 in 14 twist, appears to like my berger 68 grain match bullets, which is good news as I still had a few hundred for reloading my Sako PPC that needs a new barrel!

These are the pictures of my gun and the last target I shot. The three squares on the top left are me shooting the gun, groups were. 246 4 shots and one missfire, .356 5shots, and. 392 5 shots still doing load development. The other shots on target were a friend of mine and his girlfriend who had not shot anything larger than a.22 before.
Sorry for the crappy pictures, just getting used to downloading to the site
