In the March issue of Field & Stream they posted the results of a poll they took. One question was
" Hunters that used scoped, in-line muzzleloaders are violating the spirit of the law, and their guns are no more primitive than most centerfire deer rifles." results were pretty well divided 54% agreed, 46% disagreed.
"Spirit of the law" is pretty clearly defined by the letter of the law in most states.
Muzzle loading only, 45 cal min. black powder or substute. That is how Michigans law reads.
The in-line design has been around for years, as exemplified by Jean Samuel Pauley’s in-line system of 1812. The Germans also had an in-line flintlock design as early as 1738. So the belief that sidelock muzzleloaders are the more historically accurate traditional firearms is false. Unquestionably, the in-line style is more popular among today’s traditional hunters and shooters, says Tim Pancurak of Thompson/Center Arms. “In-lines represent the majority of our muzzleloader sales,” he said—an amazing statistic considering that T/C’s first true in-line muzzleloader was introduced in 1993. Dudley McGarity, national sales manager of Connecticut Valley Arms (CVA), says in-lines now make up about 80 percent of that company’s sales. “They have really come on strong in the past few years,” he said. “The in-line has enticed a lot of hunters to try muzzleloading. The in-line looks more familiar and is perceived to be easier to use. It is also perceived that they are more reliable and more accurate than the old traditional guns.”
The inlines just lend them selves to updateing better.
