I have (acquired in this order) a TC Seneca .36 (traditional caplock), a Lyman Remington "M1858" New Model Army, a TC New Englander .54 (traditional caplock), a .45 barrel for the Seneca, and a Pedersoli Brown Bess "Carbine" .75 cal. flintlock. In use in the western Virginia hunting conditions, I see no advantage to telescopic sights or in-line ignition at the ranges at which I will use these guns.

Obviously, I expect to have reduced "firepower" and perhaps range. I do not expect less accuracy from the rifled arms. The Bess is a smoothbore and with ball it simply will not be as accurate at ranges past 50 yards as rifled arms. If you hunt with a bow, you've already learned that your range will be limited. This is much the same thing but with a firearm.

In most cases, those buying the in-lines and scoping them are correctly perceived by the industry as wanting to hunt during the muzzleloader seasons without giving up range or power. In short, they are not interested in history, self-limitation, new hunting challenges, etc.

You need to determine the why of your muzzleloading hunting and choose accordingly. Good luck!
