RE: KRB misfires?
 

txhunter58, Any news from Knight regarding your KRB trigger assembly problems?

RE: KRB misfires?
 

Yep, I received a brand new trigger assembly today!

The only explaination was that since I didn't send the whole gun, they couldn't try it out, so they just sent me a new one???

I guess you would have to say that is good customer service, but I can't believe that they don't have some blank stock/barrels that they could use?

Also, I sent an email asking them what I should do, and the reply was that I should send in THE TRIGGER, not the whole gun.

Anyway, hopefully that will fix the problem, we will see

They know they have a problem, and it sounds like they know what it is, and they would prefer not to say. Lee

RE: KRB misfires?
 

I just got a KRB7 and I've had similar problems. After just a few shots it starts misfiring. It appears that the slightest amount of fouling between the face of the firing pin assembly and the primer block prevents the pin from fully contacting the primer, and the primer does not ignite. I had to clean this surface every shot or two to keep it firing. I am using Triple 7 primers, which (from what I've read) should be of decent quality and not excessively dirty.

I also found that the trigger assembly would not work with the thumb stud installed on the hammer. This seems to create too much inertia, so when the hammer falls the hammer safety activates and prevents contact with the firing pin. This problem goes away when I remove the thumb stud from the hammer.

Since I'm 100% new to muzzleloading I wasn't sure if it was normal to have to clean the primer area this frequently. I found this old forum topic and realized that I may actually have a problem, and that others have seen the same problems. For those of you who have sent trigger assemblies to Knight, have the problems gone away with the replacements?

I sent Knight an email, so I'll wait and see what they come back with. Thanks for the info.

I had trouble with mine also... i was using tripple 7 primers but that wasnt the problem.i looked at the primers after the misfires and they were struck very lightly....i called knight and they sent me another trigger assembly at no charge,and i sent them the defective one...havent had a missfire since with the new one.they havent got back to me yet, on the problem with the old one.

RE: KRB misfires?
 

I'm glad to hear that Knight is taking care of the problem without any fuss.

I saw the same thing on my primers. The misfires had a very light impression, compared to the ones that properly ignited. After I cleaned the fouled area these same primers all worked properly, so it seems that it had nothing to do with defective primers. I suppose it is possible that some other manufacturer's primers are more sensitive and/or cleaner and would hide this problem for a few more shots, but the problem would still be there.

RE: KRB misfires? (with 777 primers)
 

I got my trigger assembly back a few weeks ago and finally had a chance to take it to the range yesterday. The issue with the weak spring in the hammer was resolved, and that is the only thing that the service tech specifically told me was wrong. I can tell that the hammer safety clicks into position more positively on the new trigger assembly, and it stays in place with or without the thumb stud installed.

Anyway, it still misfired frequently with 777 primers. Today I picked up a pack of CCI 209M shotgun primers (only thing I could find in town other than 777s) and snapped about a dozen of them off without a single misfire. I mixed in about 6 or 7 777 primers and about half of them didn't light on the first hammer drop. I didn't clean the primer area at all during my test, so it was getting pretty cruddy after these 20 or so shots. The CCI primers lit consistently clean and dirty, and the 777 primers were hit and miss clean and dirty. I think the 777s are made of a harder material, because you can see the difference in the dimples on the spent primers. Every CCI has a nicesharp dimple. The the dimples on the 777s are less pronounced and they vary a bit.

Has anybody else had any specific problem with 777 primersand a KRB7, or with any other gun for that matter? I suppose it's possible that I got a bad batch of them but this seems unlikely. I'm going to use these CCIs and see if they remain trouble free.
