Lyman Great Plains Rifle and Great Plains Hunter

The rifle carried across the Great Plains by western pioneers and fur trappers was the culmination of percussion firearms development. This "Great Plains" rifle was designed and built by such famous makers as Hawken, Gemmer and Demick to the specifications of experienced backwoodsmen. Only the best and most reliable designs and finest workmanship were acceptable. Today, as in the 1800's, the experienced black powder shooter is looking for a very special rifle. The Lyman Great Plains Rifle, with its graceful, yet sturdy lines, is such a gun. The modern muzzleloader will appreciate its combination of strength, reliability, accuracy and authentic good looks. It is truly a black powder gun of remarkable significance.

Each Great Plains Rifle offers such high quality features as a 32", 1 in 60" twist barrel for patched ball and hunting loads, double set triggers, Hawken style percussion "snail" with clean out screw and reliable coil spring lock with correct lock plate. All guns come with walnut stocks and darkened steel furniture. The Great Plains Hunter features a 1 in 32" fast twist barrel for conicals or sabots.

Note: Lock assembly for percussion and flintlock rifles shown on page 30.

Set Trigger Assembly

Your Great Plains Rifle is equipped with a limited adjustment set trigger system. This system provides either a standard trigger for snap shots while hunting or a more sensitive "set" trigger for precision shooting.

Operation: To engage the set trigger pull the hammer back to full cock, squeeze the rear trigger until a "click" is felt, then carefully aim and press the front trigger. Be carefol-don't let the light pull catch you by surprise! You may fire the rifle without engaging the set trigger by using only the front trigger. Adjustment: Turning the adjustment screw (51) clockwise will lighten the set trigger pull; turning the screw counter-clockwise will increase it. The range of adjustment is limited by Lyman to prevent the set trigger from being lightened to the point where we feel it would be unsafe. Use common sense in this adjustment and in the use of the trigger mechanism.

LYMAN TRADE RIFLE

The Lyman Trade Rifle is patterned after the sturdy and functional guns developed for the early Indian fur trade. Designed by such companies as Henry and Leman, these original guns were much sought after by trappers, Indians and other rugged wilderness survivors. These men wanted a basic hunting gun that combined the best attributes of a hunting rifle without the expensive frills of more ornate rifles. The Trade Rifle is designed to accurately fire both patch round ball and maxi style conical bullets. It features a 28" octagon barrel with 1 in 48" twist, polished brass furniture, steel rib and blued finish on all steel parts. The single trigger is spring loaded for positive tension. Each rifle includes both fixed "primitive" and elevation adjustable rear sights. The optional 57 SML can be mounted without any modifications.

DEERSTALKER RIFLE

DEERSTALKER RIFLE

The Lyman Deerstalker is the ideal rifle for the muzzleloader whose primary interest is hunting.

Like all Lyman black powder guns, the Deerstalker has an impressive collection of top-quality rifle features. The rich walnut stock is specially designed with less drop for improved sight picture and includes a handsome rubber pad to lessen recoil. The barrel and all metal parts are blackened to avoid glare. Whether flint or percussion, all Lyman locks employ a rugged, reliable coil mainspring. The barrel has a 1 in 48" twist which will handle a large range of bullet types and weights.

The Deerstalker combines these traditional qualities with the modern features that the serious hunter demands. Each rifle features a specially designed stock with Lyman front and rear hunting sights for an improved sight picture. The shorter barrel and lighter weight make it ideal for carrying on an all day hunt. All hardware is darkened for low glare and all rifles come with sling swivel studs and a handsome rubber pad to reduce recoil. The ultra quiet single trigger is fast and efficient. Finally, all Deerstalker Rifles are factory pre-drilled and tapped for an optional Lyman 57 Receiver Sight for the most serious target shooter or hunter.
