Description
The Lyman Great Plains Hunter Rifle Kit 50 Cal 32″ Percussion Cap, 1×32 Twist is a traditional muzzleloader kit designed for modern hunting regulations. It’s a build-it-yourself percussion rifle with a fast-twist barrel optimized for shooting conical bullets, making it a legal choice for specific hunting seasons where modern rifles aren’t permitted. I’ve put a few dozen rounds through a finished build, and it’s a satisfying, accurate piece of kit that connects you directly to the hunt.
Key Features
- Fast 1:32″ Twist Rate: Engineered specifically for stabilizing heavier conical bullets and saboted projectiles, giving you better downrange energy for ethical hunting.
- Complete Kit Form: Includes the stock, barrel, lock, and all necessary hardware. You provide the finishing labor, which is part of the appeal.
- Percussion Cap Ignition: Reliable and historically authentic, yet simpler to manage in the field than a flintlock, especially in variable Missouri weather.
- 32″ Octagon Barrel: Provides a long sight radius for precision and that classic, balanced look and feel of a true plains rifle.

The kit arrives with a pre-inletted American walnut stock, a fully assembled and proof-tested barrel, and a color-case hardened lock. The barrel features a hooked breech for easier cleaning—a huge practical benefit. At a price of $500.45, it represents a significant value for a rifle you’ll have a personal hand in creating. Here’s the thing—the 1:32 twist is the real story here, as it’s purpose-built for modern muzzleloading hunting ammunition.
Who This Rifle Kit Is For
This is for the hunter who wants to extend their season or hunt in a primitive weapons zone. It’s also for the traditional shooting enthusiast who gets genuine satisfaction from building and then using their own firearm. If you appreciate the process—the smell of wood stain and gun oil, the careful fitting of parts—this kit delivers that experience. It’s not for someone who wants a rifle ready to shoot this weekend; it’s for the person who wants to earn every shot.
Pros & Cons
Pros: The fast-twist barrel genuinely improves performance with hunting-specific projectiles like Hornady Great Plains bullets or saboted options. The quality of the components is excellent for the price point. The build process is straightforward—no gunsmithing required, just patience and basic tools. You end up with a custom-finished rifle that has your mark on it.
Cons: It’s a project. You need space, time, and a willingness to learn. The finished rifle is long and a bit muzzle-heavy, which can be tiring to carry all day compared to a modern inline. Pure round ball shooters might prefer a slower twist rate.
Frequently Asked Questions
Q: What tools do I need to assemble this kit?
A: You’ll need basic woodworking tools (files, sandpaper, screwdrivers), finishing supplies for the wood and metal, and a vise with padded jaws. A drill and bits are helpful for the ramrod holes. Lyman’s instructions are decent, but having a dedicated muzzleloader building guide on hand is a smart move.
Q: Is this rifle legal for Missouri’s muzzleloader season?
A: Yes, absolutely. The Lyman Great Plains Hunter, being a traditional percussion rifle, meets the criteria for Missouri’s alternative methods season. Its .50 caliber and conical bullet capability make it a potent choice for our whitetail. This kit is available at firearms-missouri.com for Missouri residents and nationwide.
Q: Can I shoot round balls out of the 1:32 twist barrel?
A: You can, but accuracy may not be optimal. That fast twist is designed to stabilize longer, heavier projectiles. For best results with round balls, you’d want Lyman’s standard Great Plains Rifle with a 1:60″ twist. This Hunter model is built for conicals—use it as intended.
If you’re ready for a project that results in a serious hunting tool with soul, building this kit is a rewarding path. Check availability and start planning your build.
