View Full Version : need advice on taking apart muzzleloader

November 27, 2008, 06:22 PM
I recently purchased a used Investarms percussion Hawken-style muzzleloader. I tried to take it apart to clean it, but am having trouble figuring what needs to be done to get the barrel detached. I've detached the screws that look like they'd be the ones holding it in, but no luck. Any suggestions? Also, I know most of these guns are 1:48 twist, but obviously, I don't have the manual for this one. Anyone know where I can find this info for sure? Or, alternatively, if for some reason should this gun have a slower twist, will any actual damage occur if I shoot sabots out of it instead of patched balls?

There was a question very to yours close back in Nov of '07. The members with the best info back then concerning your questions concerning the Hawkin's issue were: Hawg Haggen, K.A.T., and Ted655 (whose OP started the thread). I would send them a message. They are polite and whose opinion I trust. I personally cannot provide any help here. I only shoot balls and conicals out of my Kentucky and sabots out of my in-line Wolf. Never the two do I mix.

But if you should find out otherwise, please let me know.

This should be fairly straight forward. Go to half cock, remove the ramrod. remove the wedge pin on the forend. Grab the front of the barrel and tilt it up. This barrel should have a hooked breech plug that fits into the front of the tang. If this doest not tilt then it may be stuck in the nose cap area. Work it and it will come. Later, you can relieve this tight area. You might have two wedge pins but I doubt it. Oh yes, put all the screws back where they cam out of.

Be Safe !!

Here's an Investarms PDF Manual:


Shooting saboted bullets out of a slow twist gun won't hurt it.
You can determine the twist rate by inserting a tightly patched cleaning rod all of the way down into the barrel breech, marking the rod with a piece of tape and then withdrawing the rod slowly until the tape rotates 1/2 or 1/4 of a turn. Measure the distance that the rod was withdrawn from the muzzle and then multiply that number by the denominator of the fraction that the rod turned.
1/2 of a turn in 24 inches is a 1 in 48" twist.
1/4 turn in 15 inches is a 1 in 60" twist.

Hey Pard,

I have been shooting black powder for a number of years and have used Bore Butter for treating the bore after cleaning. You gotta try this stuff . . . you won't be disapointed!
