Home Forums Hunting & Shooting Muzzleloaders Knight Disc Extreme .45

I picked up a Knight Disc Extreme 45 a few months ago. I plan on prepping it for the up and coming muzzleloader season and wonder if anyone has any BH209 experience with a 45 and what Sabot/Bullet combo they are using.

Thanks in Advance

Call Knight and see if you need to modify the breech plug. I think it needs to have the flash hole opened to .035 with a #65 drill bit. Maybe Knight has since changed, but I don't know.

To use BH209 you need to use the bare primer breech plug

I use 100gr to 120gr of BH with CCI209M primer and Hornady 200gr SST with Harvester smooth blue sabot. you can use these sabots.

Theres only three sabot you can use in your gun that's a good thing.so buy all three just to see what one your gun likes with what ever bullet your using.

Yes I ended up ordering the bare 209 primer kit... going to do some experimenting

Yes the bare 209 primer conversion will be more reliable than the plastic jackets.

110-115gr of BH209 by volume and either the 200gr SST, 195gr Barnes or the 185gr Bloodline are excellent for deer. 200gr XTPs for practice or for reduced power hunting loads. It works quite well if not pushed too fast.

Try both the MMP tan sabot and the Harvester light blue smooth sabot. The tan comes with the Barnes and SSTs.

Try the blue that is light blue an a 300 gr bullet for the 405 Winchester They work great in mine

Good thing is that there are few options when it comes to sabots...Going to try all three bullets..thanks

How much BH209 are you using

Reliable? What is your definition of reliable here?
I have no issues using the red primer jackets, even with hot primers in my Knight Vision.

So perhaps your more reliable assertion is due to the different actions of these Knights...... Extreme bolt action vs my break-action?

Hes talking about when using blackhorn209. The red jackets do leak primer gasses so that isnt exactly what you want when using BH209.

I still have to test my revolution with bh209 now that its scoped.

I am also using Blackhorn these past few weeks, burning an entire jug of it. If I'm going to exhibit blowback, then perhaps it will occur upwards of my current 80 grains (volume) powder charge.

So far, hardly nothing present and no reason for me to consider the bare primer breechplug.

Sorry but IMO he is full of it. The guy is plain goofy.

A 300gr 405Win bullet measures .411 and would be very very long in any 45x40 sabot. Your bore would have to be super loose just to load it. Loaded OD of the MMP tan is .456 with a .400 bullet. Loaded OD with either Harvester sabot is .454. Typical GM 45cal ML barrel grooves should not exceed .458-.460 at that most......The math don't add up.

Plus a 1-30 twist will more than likely not stabilize a 300gr 40cal bullet. Its too damn long. Call Hornady and get the bullet length then run it through a calculator.

Triple Se7en, if you knew anything about the Extremes, you would know they haven't made one in 45cal in many years. The old FPJ breach plugs were not the best for BH209. Been there done that many times.

The newer Lehigh type bare primer plugs have been 100% after more than 10 jugs of powder in no less than 7 Knight rifles from 45cal to 52cal. 155gr bullets to 375gr bullets. Not one hickup with a standard Win209.

Overkill thanks for the clarification. and the information.

The Disc extreme model I have is the laminated stainless.

If you really want to try a heavier sabotted bullet in the 45cal, look at Precision Rifle's 40cal Dead Centers or QTs. Cecil offers upto a 260gr but imo those are marginal in a 1-30 twist. The 240gr might work fine depending on the MV.

You could always choose a conical in the 360-405gr range. Those should work for you too. No Excuses sells a fairly affordable .451 385gr or if you cast you own, the old 330gr Gould mold will drop at about 350gr in pure lead. They used to offer that mold without a hollow point too which IMO is a better choice.

Hawks offers some 40cal jacketed bullets over 200gr but his quality is rather spotty on his HPs and Spire Points. His flat points might be better but ive never gotten any.

Thanks for the link

Prefer a sabot at least for now but will experiment.

Do you know if No Excuses manufactured bullets for White? the .50 460 bullet looks like what I used to load in my super 91. That bullet was hell on anything it hit

I think the mold is very similar to the old White conicals. Dan at Bullshop sells a similar conical and he can size them to your needs. He is only available through email but his bullets are top notch too.

This was the last email i had for him bullshopboolitsaol.com.

Knight 45 caliber Original Disc and 175 grain Red Hot sabots [or 195 grain Redhots if you can find any]

100 grains of Blackhorn 209

CCI209M primer because I was not getting reliable ignition standard 209 primers with original factory breech plug

All good:

So Lehigh is the maker of Knight's bare primer breechplug, found on Knight's website?

I haven't had any hiccups using the red primer jacket with Federal 209A. Plus the breech area of my Knight Vision remains pretty clean.

Yes, Lehigh makes the current NFPJ plugs for Knight and possibly the new FPJ plugs labeled as vented for Extremes and Mountaineers.

Lehigh also makes the bolts for Knight.

Before Knight got them Lehigh offered the conversions with removable vents like the Savage plug. Current plugs have the vents brazed in. Ive got a original prototype and 5 or 6 final release versions. Ive also got a older Knight NFPJ which is pretty bad with BH209.

No need for a mag primer in the Lehigh bare primer plugs, at least not with the originals. They were made for the dimensions of the Win209 and very well tested.

Knight still sells the 175gr RedHot and Barnes still sells the 195gr. Ive shot both and they both shot great for me. I still shoot the 195gr in my smokeless 45.

Knight now offers a 150gr too. All are made by Barnes. Personally i would waste my time with the 150gr unless you are very recoil sensitive. Even then you can buy the Barnes 40cal 155gr TAC XP pistol bullets cheaper.

So i removed the breach plug and find out the guy that sold it to me loaded the gun and forgot about it . He had 2 triple seven pellets and a power belt that I had to remove. Needless to say not very happy with the guy , I also found a pretty decent crud ring which has been coming out little by little with a lot of elbow grease.

I had ignition issues in my 50 cal DISC Extreme with anything other than Fed 209As or CCI 209Ms. Once I switched to hot primers all of my issues went away, 100% ignition with BH209 after the switch. I didn't even know that a bare 209 breech plug existed, but I saved the link just in case.

Knight sells FPJs with primers already in them.

Care to guess which primer they use?..........Win209s
http://www.knightrifles.com/product/pre-loaded-fpj-209-muzzleloader-ignition-system/

Using a hotter primer to solve an ignition issue is more of a band-aide than a solution. I actually had more misfires with mag primers when using FPJs than with the Rem STS primer which is one of the milder primers.

Its hard for me to believe a Win209 has problems igniting BH209 when it ignites all the smokeless powders ive tried in my Savage. The Savage plug is even longer and does not seal as well as the Lehigh designed Knight breach plug.

Maybe, though they actually recommend using the Fed 209A or CCI 209M over other primers.

That said, I'll probably still pick up the new breech plug.

Western recommends mag primers so that BH209 is more reliable in a larger variety of breach plugs. The new Knight bare primer plug was designed for BH209 from the start. It was also designed using a Win209 primer. One call or email to Dave at Lehigh can confirm this.

Two plugs were mainly used during the development of BH209, the T/C Omega plug and the Savage MLII plug. Consequently both are very reliable with BH209. The Omega plug is even basically flawless with a Rem STS primer.

Is there any benefit to using the Win209 over the Fed 209A or CCI 209M?

In the new Knight plug, yes. It fits the best and leaks the least. Fired primers come out nearly spotless in most cases. Other primers are shorter and normally have more blowby.

More blowby=less heat/flame/energy ect ect delivered to the powder.

I have nothing against mag primers. One of my custom builds was head spaced and the primer pocket machined for CCIs so that is what i use in it.

There is one small negative with using mag primers. They create more fouling in the flash channel. Its not really an issue in a hunting situation.
