Why do SXS barrel bore diamiters vary?

[SXS OHIO]

Wow...great info her. The reason I ask this question has more to do with originality than function. I have been wanting a hi condition graded small gauge....they are expensive! I wanted to know and be informed about this issue for value perspective. One of the guns that I looked close at has .010 over normal bore only in one barrel the other is correct. Most all the guns I buy are shipped to me after buying, no in hand inspections. As stated above when bores are not the same the flag goes up!??? I would prefer them to be the same, normal spec and still be choked properly. When old guns are priced 10-20K a feller has to know! Im still on a steep learning curve...(-: Buying is easy...selling with-out a big loss can be very tricky. Like John Wayne said...Life is hard and its harder if your stupid!!! Thanks all SXS ohio.............................

Kenny, .010 variance from left to right bore diameter on a small bore is excessive and should result in a very steep change in value and price for a graded gun. Let's put this in perspective. I have two nice DHE 20 gauge bird guns that I bought for about $2500 each. They would be $6000 guns except that the stocks are short. If the barrels had bore variances of .010, and original length stocks, the guns would be worth even less than they are with the short stocks, in my opinion.
