I took the rifle out today. It was 60 degrees but windy. I went to the 25 yard line to sight in the scope. I was on the bench rest. I started on the center bulls eye and fired three shots. The clean barrel threw the first shot high, but after that the next two touched.
I then made an adjustment of 16 clicks to the left and fired three more. They all touched. So I fired two more just to make sure the rifle was on. I was very pleased with the group so far. In fact it was getting hard to count shots. I was shooting Hornady 300 grain XTP in a Crushed Rib Harvester Sabot. I was using RWS 1075 caps. Ignition was perfect. I was swabbing every third shot. And shooting 100 grains of Triple Se7en 2f.
I then swabbed the barrel clean. I wanted to try some of the .451 260 grain Nosler Partitions in Nosler sabots that I purchased. Again, I was shooting 100 grains of Triple Se7en, the same cap, same distance, swabbing every three shots. They loaded very nice in the rifle. I was shooting them at the lower right corner bulls eye. The five shot group with them was very impressive. More testing will have to be done with these as well.
I then again swabbed the barrel clean and had some American Pioneer Powder 3f in the bag left over from the last range trip. So I loaded up some 10mm 200 gr XTPs in the blue MMP sabots with 100 grains of APP 3f. I shot for the upper right corner bulls eye. The first three shots were real good. Then I was almost out of powder and would shake some into the measure and top it off with pyrodex RS. In fact the last one was powder dumped into my hand, then into the powder measure, then the Pyrodex added. The bottom two are combination powder shots.. over all they did well.
I cleaned the barrel again and went after the upper left corner bull. This time I loaded 100 grains of Pyrodex RS and a 300 grain Hornady Mag Express in the sabots that came with the bullets. I had a perfect three shot group going and then had to shoot two more to be smart. Still a very good group. I swabbed every third shot. I was going to shoot six shots at that corner target, but a red squirrel had the gall to sit on a stump down range from me about 45 yards. So I wasted a shot. It flipped him in the air real high, but he did take off running. He might have a shaving in his toe or something.
Then to see if I could keep loading, I aimed at the lower left corner bull and shot two of my home casted .457 pure lead flat point bullets. The mold says they are supposed to be a 405 grain. Well my scale puts them more around 423 grains. One bullet was deformed a little I noticed. I was shooting them with 100 grains of Pyrodex RS. They really have some down range thump when they hit.
This is a very sweet rifle to shoot. Because of the weight of the rifle, recoil is next to nothing. With the 1X scope, it makes a very good aiming device for me. Next time out will be 50 yards, and then back to 100 yards. After all deer season will be here in November...
