T C Thunderhawk Thimble Screw

Never attempt to pull a charge from your Thunderhawk® until you are absolutely certain that the firearm is deprimed (percussion cap, removed from the nipple). Do not attempt to pull a charge from any gun until the powder charge has been rendered inert (barrel removed and its breech section submerged in water for at least one-half hour) as explained in the following text dealing with pulling a charge. AN ACCIDENTAL DISCHARGE CAN CAUSE INJURY AND/OR DEATH TO THE SHOOTER OR BYSTANDERS AND DAMAGE TO PROPERTY.


Under normal conditions your ThunderHawk® is unloaded simply by firing it into a suitable and safe backstop. There are, however, some conditions under which the firearm cannot be fired and the charge must be pulled.


1. If the projectile is not seated firmly against the powder charge, stop immediately! Do not attempt to fire the rifle. You must pull the charge and clean the barrel.

2. If the rifle is loaded in a proper manner yet fails to fire after repeated repriming and clearing of the ignition ports (explained in "Ignition" section).

3. If you are at a location that is unsuitable for discharging the firearm before transporting it.



1st Step - After making sure that the gun is unprimed and uncharged, lower the striker to the "fired" position by pulling the trigger while holding the striker handle and slowly letting the striker go forward until it contacts the bare nipple.

2nd Step - Remove the ramrod from the thimble(s).

3rd Step - Remove the front stock assembly screw by turning it out counterclockwise (as viewed from the bottom of the gun). Then remove the screw from the back of the trigger guard (the front trigger guard screw holds the trigger guard to the stock, it does not hold the barrel/receiver assembly to the stock).

4th Step - The barrel and receiver may now be lifted out of the stock.

5th Step - The large receiver end cap at the rear of the receiver can now be removed by turning it counter-clockwise. This cap is under spring tension so be sure to maintain a firm grip on it while turning it out. Remove the receiver end cap, the spring and the striker handle retainer.

Once the gun is disassembled, it is now possible to proceed with the process of pulling a charge.

Secure a pail of water (hot if possible) and submerge the breech section of the barrel into the water. Make certain that at least 8 inches of the breech section is under water and allow the barrel to remain submerged for at least one-half hour. The barrel should be transported only after water has totally saturated the powder charge and rendered it inert.

The charge should be pulled by using a Thompson/Center Ball & Bullet Puller as follows:

Carry the barrel to an area where you have access to a strong vise and where you can work without distraction. To ensure that the charge has not dried out and that it is completely inert, re-soak the breech section in very hot water. While the breech is soaking, pour some hot water into the muzzle end (flush with the muzzle). This will soften the powder fouling which has accumulated in the bore and ease removal of the projectile.

After one-half hour, remove the barrel from the water. Pour the water out of the muzzle and wipe excess water with a rag. Pad the jaws of your vise with two blocks of wood and securely clamp your barrel so that you have access to the muzzle end. Use care to ensure that the barrel is not marred in the process of clamping it. Be equally certain that it is clamped securely.

Thread a T/C Ball & Bullet Puller of the proper caliber onto your ramrod and slip the ramrod into the bore until the screw on the puller contacts the projectile. Rotate the ramrod slowly clock wise as you tap lightly on the end of the ramrod with a hammer. As the puller screw bites deeper and deeper into the soft lead projectile, the ramrod will become difficult to turn and it will require the use of pliers. Pad the jaws of the pliers so that you do not mar the ramrod. Once the puller screw has embedded itself firmly into the projectile, pull out on the ramrod and extract the ball or bullet. In actuality, this process is somewhat tedious and it will require your patience. When working with a badly fouled bore, the puller screw may pull free from the projectile several times before you can successfully extract the projectile. If you are persistent, you will succeed!

After the projectile has been removed from the bore, clean the bore, barrel and parts as explained in the "Cleaning" section and reassemble the firearm.

If for any reason you are unable to remove the charge in the manner recommended, soak the barrel in very hot water for one-half hour. Once the powder has been rendered inert, take the barrel to a qualified gunsmith. Explain the condition and ask that he clear the barrel.
