Question for Knight Rifle owners who are using BH209:
Which breech plug have you found is better for igniting BH209 in cold & rainy weather -- the breech plug for the red plastic jacket or the breech plug for the conversion non-plastic jacket?
During the summer and fall, I used both breech plugs with BH209 and did not have ignition problems in my Knight LRH with CCI 209M primers. Yesterday, though, I was hunting in colder (40s to lower 50s) temperature with a light to medium rain (not a downpour). Bumped one deer but no shots. At the end of the day, I discharged the rifle and there was a definite slight hangfire. Obviously, I was disappointed (and annoyed) when that happen. I was using the breechplug for the red plastic jacket and CCI 200M primer. Which breechplug do you use in colder or rainy weather?
I still hope that Lehigh Bullets (or someone) comes out with a breechplug for the Knight that works for BH209, if that project is still in the works for Lehigh. Or, maybe Western Powders can take a look at the ignition problem in the formula or look at modified primers for their product.
I like BH209 and my Knight Rifle. But I am starting to think that the reliablity of BH209 is too big a problem for hunting.

To get better reliablility with your Knight, you'll have to go to a chain shop and have your breechplug drilled out to .036 in. or so.

cantremembermyid I have been using a FPJ breech plug and I am not having any trouble as long as I load a snug sabot and compress the load tight.... A couple of other points... I am thinking Randy's suggestion of .36 is a bit much - it will definitely probably set the powder off but it will also allow a lot of blow back back through your breech plug - could be a dirty mess. Lehigh Manufacturing is at some point very soon going to release a completly new NFPJ breech plug with a Lehigh vent liner installed in it - to solve these problems. I do not believe it is ready quite yet. In the meantime because I really like the FPJ better than a bare primer, I have modified my current FPJ breech plug and installed a Lehigh Vent liner - it is a domed liner that helps reduce blow back and the flash hole is .32. Here is a pricture of my completed project for the Knight...  This group of pictures explains it more as I converted an Omega BP also...  |

Interesting thread Sabotloader. Does your modified Knight plug
have a lot less blowback than the oem plug? I will be checking into Lehigh's plugs. Hopefully they will be out soon. I really like my Knight Extreme, and less blowback will make it even better.

I believe it does... I think the domed vent liner really helps. One thing I will do next is make the cavity that the ventliner sits in bigger - increasing the volume blowback that can held...
Right now the cavity is just large enough to get the Vent Liner in...

Thanks everyone for your info. Your info is quite helpful. These forums are a great way to learn things.
I now see that I need to enlarge the flash hole, and need to find someone near me that can do the Sabotloader's remedy on my plug.
Sabotloader -- What exactly does a vent liner do in contrast to just enlarging the flash hole? I bet the answer is a simple one, but I don't know it.

The main thing about the Vent Liner - it was made to set off smokeless powder.... that added feature in the design is help reduce blow-bac back through the flash hole. In most case the flash hole is at the bottom a cone - so blow back is directed to and into the flash hole.... the Cone shape of the Lehigh liner directs a good deal of this away from the flash hole.

cantremembermyid,
Like Sabotloader I to use a recessed plug in my Knight T-bolt. I converted it to use 209s and also use the Savage style vent liner. I did extensive work to the bolt to safely hold the primer in a non Plactic Jacket BP. This has worked well for me with BH209. Last season I hunted the last 2 weeks with the T-bolt using BH209 here in NY. There were many cold rainy days that I carried and used the rifle.
Good primer fit is very important. The original 209 conversion from Knight for the T-bolt was a Joke! The plunger with that kit was pointed and would pierce the cup of the primer. This would fire Pyrodex but didn't light any BH209. It also allowed the primer to blow out of the BP and make a real mess. after just 12 popped primers the plunger was stuck with crud and would not move. My mod to this conversion now lock the primer in the BP and the Shot Gun style tip on the plunger fires the primers just fine.
