So I decided I'd write an article on the takedown process of a Thompson Center Thunderhawk Muzzleloader. The Firehawk is done with the same method.

So first thing is to take off your scope if you have one mounted to your muzzleloader, and take your sling and ramrod out:

Next steps are to take the screws out of the stock:

Where they are on the stock:

Screws taken out:

Here is the stock with the barrel taken off:

Barrel:

Now we take the breechplug off. Remember this is under spring tension, so when you break it loose with the screwdriver, push down and twist at the same time to keep it from flying off:

Breechplug off:

You can see in the pic above the breechplug hasn't been cleaned in awhile.

Here is the recoil spring:

It comes out by just pulling up on it and twisting:

Next, the bolt handle comes out by sliding the bolt back and pulling the bolt handle straight out from the side of the muzzleloader:

Once it is out, this little piece will come out of the bolt if you tip it backwards. Make sure you don't lose it by forgetting it's in there:

That little piece is what the spring sits on inside the bolt.

Next step is the bolt removal. I use my finger and push it backwards, while my other finger squeezes the trigger so the bolt will come out:

Bolt removed:

Next, wipe off all of the old oil/grease on all the parts:

While you have it apart, put some oil in this hole on the trigger assembly so it can be greased:

Now put some oil onto the bolt:

And start the bolt back into the chamber:

Squeeze the trigger and it will drop down to the proper place:

Then put your bolt handle back in. All it does is push in:

Then put the little piece the springs ride on in:

Then our spring goes back in. Put some oil onto the spring and push it into the bolt:

Then twist it and it will seat:

Now we put our breechplug back on. Push down and hold while turning it to tighten:

Then put your stock back on and we can work the bolt. This is uncocked:

Cocked and off safety:

Cocked and on safety:

Now that we know it works, we can remount our scope and put the sling and ramrod back on:
