Well I took the new Black Mountain Magnum Rifle out to the range today. I was set up at 50 yards. I had noticed the sight looked kind of low on the ramp but decided to shoot anyway.
I started out with 70 grains of Pyrodex P, no wad, CCI musket cap, and a 450 grain UC Short Mag conical. Shot #1 was on a clean barrel. #2 was on a fowled barrel. I them made a slight sight adjustment and swabbed the barrel clean. #3,4,& 5 were still too low, so I swabbed the barrel and made another sight adjustment. The next six shots were made without swabbing the barrel shooting the UC short conicals that I make at the house here.
I then swabbed the barrel clean and shot some 375 grain Buffalo Bullet SSB's with the supplied sabots. They loaded very nice. I swabbed between shots. I was shooting 90 grains of Pyrodex P with these conicals. I was kind of pleased so far.
I then swabbed the barrel and loaded 110 grainsof Pyrodex RS and some 250 grain Barnes Expanders with red sabots. They loaded very hard. Holding a 6 o'clock sight on that small piece of duct tape I was very happy with the Barnes and the way they grouped.
It was 74 degrees out, and very windy. I had a strong cross wind on the range, but it did not seem to effect the projectiles too much. For the first time outwith the Black Mountain Magnum I was kind of pleased. The musket caps provided an excellent ignition to the rifle.
