I don't know who got appointed to be Daniel Webster, and define a fowler as one thing or another, but like most P/C arguments, its sounds particularly silly. My fowler has a rear sight on it, because I asked for one, intending to shoot PRB in the gun. It is half octagon, half round barrel, and is thoroughly an American made gun. It immitates no particular style of historic firearm. It has a left handed Flintlock, too. It has more of the attributes given to most fowlers by most writers, than not, so its a Fowler. Not a smoothrifle. If the range rules at Friendship call for removing the rear site to qualify to shoot a particular match, I won't shoot that match. My life will not end because I don't meet someone's elses criteria. They also don't get my entry fee, or my support for their shooting match. Its their choice. Its their shooting match.
What is the reason and source for this drive by so many shooters to build or buy a gun that pleases someone else? If you are custom builder, like Mark, of course you build guns to suit the costomer's taste. That is why you are in business. But I have not met a builder yet who claims a particular barrel will only shoot well if its married to a particular style of stock, or sights, or trigger, or buttplate, or has or does not have a patch box, etc.
I know this is heresy, here, but am I the only one who had a gun built to fit me, and not some picture of a gun in someone's museum, or gun collection?
