Since the original Knight Disc rifle I own was converted over to a Lehigh Generation II system for the breech plug, I have to admit a few things. I have really liked shooting the rifle in the past but hated all the loading of the primer jackets, etc. With the Lehigh Gen II system that is all in the past. I just drop a primer into the opening of the breech and push the handle down to **** the rifle, and we are ready to rock and roll. It has really made me want to shoot the rifle more. And I have been.

Today I wanted to push the Knight with a lot of bullets. And a lot of powder in some cases.

RIFLE... Knight Disc .50 caliber 1-28 twist 24 in barrel Lehigh Gen II
breech plug conversion

POWDER... Pyrodex RS
PRIMERS... Winchester W209
PROJECTILES... 250 grain Hornady XTP, 250 grain Bonded Shockwaves, 375 grain Buffalo Bullet pure lead SSB (* the SSB is a pure lead with a slight hollow point)
DISTANCE... 75 yards bench rest

SWAB SOLUTION... Rusty Duck Black Off

I started the shooting on a clean barrel with 90 grains of Pyrodex RS and the 375 grain Buffalo Bullet SSB. This is a good stout load but the design of the rifle eats that up perfect.



I was real impressed with the load until #5 pulled that little stunt. I guess I can live with it, but I really saw no reason why it jumped out of the group the way it is. In fact after the smoke cleared I fully expected to see it with the other four.

I then kicked the powder charge up to 110 grains with the same bullet. I knew this would get exciting.



Again, the rifle ate the recoil up real well. And that would make a heck of a hunting load. Lots of powder with that heavy bullet.

I then swabbed the barrel very very clean. I changed to the Hornady XTP and decided to try 120 grains of loose Pyrodex RS. This was interesting. Also a lot of smoke when fired.



Here I was swabbing every second shot, and every second shot was a semi flier. So is swabbing that important when shooting a max charge? I guess so.

Again, I swabbed the bore clean and then changed to the 250 grain Shockwave Bonded with a MMP sabot.



This is the first time I shot the bonded Shockwaves. It is my understanding that these are for larger game like elk, moose, bear.. correct me if I am wrong. The bonded is not needed for deer. The accuracy was exceptional. The prior XTP test showed me the need to swab and I was swabbing after each shot. Then #5 pulled a semisane on me. Again, after shooting I really expected to see it in the rest of the group. So for kicks, I did not swab and shot #6. Actually this rifle always did shoot Shockwaves well. But these bonded did real well with that powerful of a powder charge.

Next time out, it will be conicals...
