12ga Reproduction Choke Help

[TNR]

After an long search I recently purchased a 12ga repro - 26" barrels marked IC/Mod. The gun has been used and I cant be for certain that the chokes have not been modified from original.

Using a galazan bronze gauge (which has always been good for me in ballparking the choke in classic guns) the barrels measure at almost Cylinder and not quite Cylinder.

However, using my micrometer I am getting .727 (R) .724 (L) which, given my research here, assuming a .735 bore equates to .008 (R) and .011 (L)

I've found several posts in the forum that indicate this is proper for IC/Mod reproduction barrels.

As I am still in my purchase inspection period - looking for some feedback just to make sure this is square with factory reproduction chokes.

Any feedback is welcomed.
