My new rifle got here last week took it to the range and WOW I'm about ready to throw it in the river (not quite Knight has too good of a service dept for that) started 100 gr pyrodex, .430 240 gr rem bullet (don't knock it shoots in my MK-85s, the wolverines, big horn and T-bolts I've had), shooting sort of ok 3.5" at 50, powder ran out, opened new can went to 6" groups, went and got a new jug of T7 back down a little, bore felt rough so I went ahead and got a pack of power belts to rub the lands a bit, last 4 shots 90 gr T7 and 245 gr power belts was 4". I will grant that in my experience power belts don't shoot as well as sabots in Knights however this is not good. I called Knight and got the shoot the .451 bullets in the black sabots, just wondering about someone elses opinions

I took my Disc rifle out today and the first three shots I took were with the Thompson Center Mag Express 240 grain XTP's on top of 100 grains Goex 3f. I was not happy with that. I got to thinking that perhaps this rifle was one that liked the heavy weight bullets, so I decided to try something real heavy.

I got some Remington .457 diameter 405 grain FP bullets and loaded them in to orange Knight sabots. I put them on top of 100 grains of Goex 3f and shooting off a bench rest using the small fluorescent circle as my POI using a full 6 o'clock hold (my front dot would hide that fluorescent dot), I loaded the red tape part of the target with the big 405's. It was shooting around a 2" group. Something I guess I could live with since I was shooting the open sights. Plenty good for where I want to hunt with this rifle at.

Tomorrow I want to try these at the 100 yard station. The Knight Disc so far has been a real impressive rifle to shoot. The one draw back of the rifle is it is quick to fowl out. Also it is a real PITA to clean compared to most of the other rifles I own. The other thing is the orange discs, but I am getting used to that. I was reusing the spent ones from the day before. Although the primer was loose in them having been stretched from the first primer round through them, they still worked fine to hold the primer in place for the second shot.... I have finally got the C-tool bolt extraction down to second nature and it is nothing to breaking the rifle down....

With a decent scope, 150 grains of powder or pyrodex and 350 grain bullet, I have no problem shooting 150-200 yards at the range. Usually only need 50-75 yards in the woods. No open fields where I hunt. I have the original DISC with the orange inserts, have used it for 7 years and love it.

Did you try any powerbelts before you started shooting sabots? I always fire a package of powerbelts out of any new gun before I start accuracy testing. I just feel it helps the bore break in some.



Groups fired from Disc Extreme from Left to right. 260 Platinum tip/HPH 12 sabot, 200 SST/Shockwave/MMP Blue sabot, and 195 gr. Barnes/MMP Blue sabot. All fired with 100 gr of Triple Seven. Left most target, group to the right measured 1 1/8" CTC. The left group did 1" on the nose. The other targets were new projectile tests.

My standard load for years in my Disc was 100grs of Pyrodex or Goex
and a 300gr Barnes copper bullet....Currently I am sighted in with 90grs
Pyrodex and a TC 250 Shockwaves...grouping about 2-2 1/2 inches at 150...
If you can find last years Shockwaves with the shorter sabots...they might
help..my groups went from 2 1/2 at 100 with the Hornady SSTs to one ragged hole at 100 with the shorter sabots in the TC package...For some reason I can't duplicate with the MMP short black or the Mag sabots...So
I went to Dicks and bought 6 boxes...

Also...for some reason my Knight has never liked 250gr bullets, until I tried the Shockwaves...Just prefers longer bullets....

Go figureusing 90 pyrodex it likes 240 TC cheap shots, the 295 power belts aren't bad either about 1.25 at 50 thanks for the imput

Powerbelt bullet diameters are a little different. They are really designed to be shot out of cva's because of the barrell diameter. I believe that they can be shot out of guns other than cva's but they were really designed to be shot out of the cva's. No joke. Look up the diameters of bullets and look up the diameters of the cva barrels. You'll see for yourself. Then look up the diameter of other barrels. You'll see the difference in a hurry, I worked at Gander and we had lots of complaints until we started checking diamters.

While that is true that most BPI barrels are suited to shoot the Powerbelts, many of the other rifles although not intentionally are made to, will also shoot Powerbelts very well. A lot of it I am sure depends on the barrels. Also if you shoot and fowl some of your rifles as many do in their first shots. they then find that without swabbing, the Powerbelts make an excellent accuracy, fast loading second shot. All you can do is try your rifle and see how they like Powerbelts.

How does one easily determine what the barrel inside diameter is other than using tools. Are these figures printed somewhere? How about bullet diameters?

Thanks

Without tools, that is very hard to do. A bore gauge works well for this also. The inside diameter of barrels can vary from manufacturer to manufacturer, model to model, and even rifle to rife. There is no set standard that says all these barrels will be .501 diameter. That is one of the reasons some rifles, even the same make, will shoot one sabot bullet combination fine but a different one will hardly get it down the bore. Makes it kind of handy for bullet sales doesn't it.

As for the diameter of bullets, normally they are listed by the manufacturer. If your rifle has a hard time loading sabots, then you are better to look at the .429 or .451 diameter bullets for the .50 caliber.
