The flintlock Pennsylvania Long Rifle (aka the "Kentucky rifle") had barrels mostly in 1:60 to 1:70 twist and were originally made to shoot
ONLY round, patched rifle balls. Such rifles were used during our Revolutionary War & the War of 1812 era... circa 1776-1820 at which time the percussion cap ignition system was developed. During the years between 1830 to 1860, many flintlock rifles were converted into percussion cap rifles.
The conical bullets came with the Civil War era (1860-1864) and the use of the shorter barreled (often "Hawken" style) percussion cap rifles having 1:48 twist barrels which can handle both conical bullets and round, patched rifle balls.
With a
modern Hawken replica rifle, you can use either the round, patched ball OR a conical bullet in their 1:48 twist barrels.
However, with most Pennsylvania Long Rifles (or "Kentucky rifles") with the 1:60 to 1:70 twist, you need to use a round, patched rifle ball
ONLY. These rifles are adequate for taking deer in .45 or larger calibers with the most popular caliber being the .50 caliber for deer and the .54 caliber for larger game such as elk or bear.
Good luck and make
GOOD smoke...
