Over the last two decades, in-line muzzleloaders have become increasingly sophisticated and user-friendly, and Thompson/Center has been one of the leaders in modern muzzleloader innovation. The company’s newest .50-caliber smokepole, the Thompson Center Impact SB, is easy to operate, accurate and, with a starting MSRP of just $263, it’s also an excellent bargain.
Thompson Center Impact SB Features
The Impact SB utilizes a break-action design that incorporates an ambidextrous sliding hood. The hood surrounds the top of the breech and, when retracted, allows the barrel to pivot downward, providing easy access to the breech plug for loading, unloading, and cleaning.
Another key feature of the Thompson Center Impact SB 50 Cal rifle is T/C’s Speed Breech system. The breech plug is equipped with triple lead threads. That requires only five turns to fully insert and is designed to prevent seizing. By simply removing the breech plug, it’s easy to clean the rifle’s bore. While removing corrosive black powder residue, which improves accuracy. The Thompson Center Impact SB is designed to function with 209 primers and a breech-plug wrench is included, though it likely won’t be required if you stick to a routine cleaning regimen.
There are five different Impact SB models currently available. All of which are equipped with 26-inch, 1:28-inch-twist barrels and synthetic stocks. Blued rifles are available with either a black or Mossy Oak Bottomland stock, and models equipped with T/C’s Silver Weather Shield finish come with your choice of Mossy Oak Bottomland, Mossy Oak Break-Up Country, or Realtree Edge camo stocks.
All Thompson Center Impact 50 Cal stocks come with a 1-inch removable stock spacer. Thus, allowing you to adjust the length of pull from 13 to 14 inches. There’s a dense black recoil pad to help absorb kick. The raised comb naturally aligns the shooter’s eye with the included Williams fiber optic sights or a scope. The rear sight is screw-adjustable for windage and elevation and features. Two orange fiber optic dots, while the front sight comes with a single green dot.
