Tapered and flared barrels
« on: February 15, 2010, 02:34:27 PM »
Not being able to handle any original longrifles, I have been studying as many pictures as I can.  I have yet to find any photos of barrels with the extreme taper and flare of those made today.  Some in fact I swore were straight untiL I laid a straightedge along it to detect the "swamp".  Has anyone measured original barrels to see what the average taper and flare was?  Are there any barrel makers that make a less "swamped" barrel?  Some of those I have looked at, the profile seems closer to a straight barrel than to what is available today in a swamped barrel.  Any thoughts?

I would not judge barrels by what you can tell from pictures.It's true that later barrels had much less flair than early barrels alot depends on time and place.Some of the most popular barrel patterns have too much flair for later guns.In order to determine how much taper and flair you need you must first decide what rifle you want to build.John Getz of Getz Barrels(570-658-7263) has a couple of nice barrels that he runs with much less taper and flair than the standard production patterns if you decide thats what you need.

One has to study old guns a lot to determine how much taper and flair the barrels had.     Most of the barrels made today
are copies of patterns that we made years ago.   Let's take a look at the 38" series of barrels that we made and called
our "transitional" series.   These all evolved out of the heavy "D" weight barrel which was made as a copy of the barrel
on the Edward Marshall rifle.......can't get much more original than that.   After looking at the nice profile of that barrel, we
thought, "gee, I wonder how that would look in a smaller version, thus we came up with an A, B, C weight barrel to go with that D weight barrel.   They all looked good and soon became popular.....be they right or wrong, we were in the business to make and sell barrels.    The 44" series of barrels that were known as the "Bicentennial" barrel was designed
by John Bivins in order to produce those Bicentennial guns.   Once again, we also made some smaller versions of this barrel which became popuar.......we later changed the series and called it our "Dickert" barrel.  If you start to study those
old guns, you have to realize that most of them were of the hand forged type of barrel and many did not have a huge taper and flair to them.   Today, people don't want that muzzle heavy feel to a gun, and most are happy to live with the
barrels that are now being made, and how many guys for example, look at a Jim Kibler rifle and say, that's a nice gun but
the barrel has too much flair.....come on, gee whiz...............Don

A lot depends on the era as well. 1790-1820 barrels would have a different profile than earlier barrels.  It's a lot of extra machining to produce a swamped barrel, and customers mostly want to see that is sure nuff is swamped!  It's a question as to whether customers would be happy with the sort of profiles found around the War of 1812 or not.  But a good question as that bicentennial is coming up!  I don't want to hijack but there might be an interest in barrels suitable for rifles of that era now.

Jim Webb's book on "Rifle Gun Triggers, Locks, Fitting, & Etc." has a chart giving dimensions of 9 different barrels that he measured. It gives the measurement at every inch from muzzle to breech.
A 43" sample starts at .900, drops to .870 @ 6" back and stays there until 15 " back and flares to .920 @ breech.
A 45" sample starts at .935" , tapers to .820 6" back and then tapers steadily to a breech dimension of 1.205" @ the breech.
 Neither of these are remotely close to what is commercially available today, but then again a CNC milling machine is much more versatile that a grindstone.

Thanks, lots of good info.  I have a smoothbore that I really like, so I don't know if I'll do a rifle or not.  I have  however been studying up on them. Thanks again.
