The book on American fowlers doesn't mention Smooth rifles at all , they are all called Fowlers .The figures I quote are from a study carried out by the Kentucky Rifle Association . Re the Lancaster/ Kentucky fowlers verses the rifles the differences averagely are . Rifle = grip rail trigger guard , double set triggers , butt stock with a cheekpiece and a flat bottom , butt plate with 3 facets and a squared tang ,patch boxes wooden and brass, barrel octagonal and average 44 inches long .
Fowler: trigger guard rounded bow , single trigger , butt stock oval section average butt thickness was 1.8 inches , butt plate rounded with elongated tang , patch box if fitted wooden on early guns brass on later , average barrel length 47 inches , calibers range from .47- .74 with an average of .58 . 80% had octagonal to round barrels 20% round barrels . None had octagonal barrels . Barrels fell into two groups .70 inch or .110 inch thick . The guns with the thicker barrels are now known as buck and ball guns . 85% had rear sights .
I like the idea of a versatile smooth rifle and maybe one day I will get one with a 50" or more octagon to round barrel , with .70 " walls , a round trigger guard and round butt plate , no cheek piece , in 20 ga and with a single trigger .
