Whats wrong with my Knight Bighorn?
« on: December 10, 2013, 06:37:13 PM »
I think something is wrong with my Bighorn. If you pull the bolt back in the loaded/fire position, then tap the back of the bolt where secondary is it slides forward to fire. I do know it won't fire because secondary is not screwed out but wth?  BTW since this started happening I noticed that if I put my finger on the trigger and just barely touch it with the primary safety off it will fire. Is there something wrong with the trigger mechanism? Any help would be appreciated. TIA

If you cleaned it you might take it back apart and then put it back together again in case something just was;nt fitted right. If that does;nt work I would get it looked at that's not safe.

I put a thumbhole stock on it two years ago and have Killed two elk with no problems. I clean this gun like like it's a diamond ring. Something went wrong with that little tab that rides in the groove of the bolt I think.  I have also taken it apart and lubricated again with no change. I'm at a loss.

My bighorn fired last year as I was starting to come down on a bull (shot over its back).

I was like WTH!  started checking, and my trigger was less than 1 lb (I have a trigger scale for competition)

Called knight, and they asked if I was comfortable adjusting it to higher setting.  I was, they told me how to adjust it.

My hunting partner came over to witness my adjustment....because he hunts in close proximity to me.....self preservation.

But I DO NOT know why it changed suddenly.  I had cleaned the rifle and trigger before the hunt, the next day had the problem.

I have not had it happen since my  (re)adjustment.

For some reason the trigger assemblies coolect a lot of crude... I have now started just removing the trigger assembly after cleaning the rifle and flushing the trigger with carb cleaner - re-lube it an install it again... Probably would be easier just to remove the trigger while cleaning period...

The sear pin area really just collect gunk...

Keep shooting muzzleloaders - They are a blast!!

Mine changed after using brake clean and compressed air to clean.  I lubed all pivots with oil and greased the sear points.  I first thought my competition trigger grease was too slick(?).  Cleaning again did not restore the trigger pull.  That is when I called and then adjusted the trigger.

Thanks for the offer, I will clean up the trigger assembly and see if I still have the problem. If I do I may take you up on your offer. Thanks

I had the same problem with my Wolverine .54 (uses the same trigger assembly), after I dropped on the floor while cleaning it.
I sent it to Knight's gunsmith to hopefully rebuild or fix. found out the trigger assembly is not made in house and not repairable. All I was told was that here was something internal causing it to bind up. Have a new one coming $126.00 delivered. Not too happy, thinking of switching to a T/C.

I had a problem with my trigger to. If you pulled the bolt back it would not catch the shear. I lubed the hell out of it. I tried it again with not problem. I shot it with out a hitch. Reloaded her and pushed forward the safety then rifle fired.  :yike: Scary. I pulled apart every thing in the trigger Assembly cleaned and lubed. I still didn't trust the trigger pull. So I adjusted it to have more meat on the shear/trigger. I now clean and lube the sh-t out of it now.

Wow.  I find it incredible that knight did not mention the sear when I called them.....only how to increase the trigger pull.

sabotsoader, do you have a list of the safety tests to go through?

My buddy and I checked trigger pull with safety on.  With safety off, we bumped, thumped, jostled and tried anything we could think of to try to make the plunger drop.  It was all good.

Another note: Does everyone need to squeeze the trigger to get the breechplug tool into the action.  I was wondering if this could cause some trigger issues (if trigger was not squeezed)

You have completed the safety tests that I would recommend.

With the height of the sear on that trigger I always try to depress the trigger when installing and removing tools from the breech.... OR remove the trigger assembly altogether.  And yes it certainly could cause trigger issues if you applied enough force.

I have had my Bighorn for over a decade and have not had an issue.  However I clean my barrel and flush my trigger mechanism with boiling water after every trip to the field and range and then relube.  The boiling water flushes old oil out and heats the metal enough to where any condensation evaporates.  No solvent, no messes. 
It is foolish and wrong to mourn these men.  Rather, we should thank god that such men lived.  -General George S. Patton
