12" or 14" barrel

[AMGClassic-ugh]

Lets say your test firing 2 barrel lengths indoor with the same gun/paint. So, the weather will be equal and the paint/gun are the exact same when your test firing.

In order to get more range and less unaccurate shots, its best to choose a 12" barrel then a 14" barrel correct?

probably zero measurable difference. anything more than 14 in and you might notice differences. but between 12 and 14 there wouldn't be any.
