Last week after getting home from my second shoot with the re-claimed Knight Super DISC I decided to strip clean the barrel to get all the oils and residues out as I wanted to treat it with Dyna-Tek Bore Coat. I purchased this Super DISC knowing that the barrel was probably pitted, but believing it could be saved. I had already ran a JB bore treatment on the bore and installed a new crown. The shooting I did with the rifle earlier in the week convinced me this rifle was going to work well. The bullet I want to use in this rifle is a 40 x 230 grain Lehigh brass bullet. Because of its weight it is very long and requires a fast twist bore to stabilize the bullet.
This is the bullet I am talking about.
It doesn't look abnormally long here in the picture shown above, but when you insert it in a sabot it becomes very noticeable.
The Super DISC with its 1/20 twist rate is an excellent rifle to shoot this bullet.
Because everything was working out so well as have stated above I decided I really wanted to treat the bore with Dyna-Tek. I actually even read the directions that came with the product.
After applying the Ceramic fluid in the bore the last part of the instructions was allow the bore to dry and then shoot approximately 6 shots through the bore to apply heat and pressure to the bore. Todays shoot was to get this task done.
I normally do not shoot BH but in reality this would be an excellent powder for this application... it burns hotter and longer than T7 - so it should really accomplish the task. I pre-measure out 120 grains of BH and dropped it into powder tubes. I loaded 10 tubes, thinking a couple of extra couldn't hurt. Equipped with this I really felt I could 'cook' the barrel with shot after shot with no or very little cooling time between shots.
I walked 6 birds out to 100 yards walked back loaded and began shooting. The first 6 shots went just as planned - 6 shattered birds. This set of pictures kind of shows the results of the shooting.
I still had 4 shots left and began searching the ground in the snow looking for additional targets. I found chunk of stubble sticking out of the snow at about 107 yards according to the range finder. Two of my remaining shots were shot at this target of opportunity with excellent results... Then I looked for a more distant target - found a chunk of stubble way up the draw. Tried to range it from the bench but could not get the finder to get a reading over the snow - I moved the finder horizontally to a bare spot of earth and it returned a reading of 230 yards.
Loaded the rifle and sat down at the bench. The scope I am using is a rifle scope with a 600 yard ballistic reticule. There is a picture of the reticule in the next composite. I used the second mil-dot under the cross hair and held the dot right on the target. First shot was just right and under the target. Loaded up the final shot - used the same hold but moved the dot the left edge of the piece stubble, touched the shot off. It definitely came left and it was identical it printed right next to the first shot.
I walked out to get pictures and also to shoot a range back to the truck... It turns out I was about 5" low slightly right with the first shot and almost direct on with the second shot. Shot the range back to the truck from the target - 240 yards. Over that open field the range really seems much farther but without trees or any thing to get a apparent size and distance of any thing.
Gotta go clean now...
