Just got back from the range. I decided to wait to the last minute to more simulate actual hunting conditions with snow and cold included.
The 330 grain home made, Lyman cast hollow point, .458 inch bullets performed well at 100 yards. A three Shot group of 2.5 inches is the best I could do today, but I am pleased. I believe a higher magnification scope would improve the group. I am limited to a one power scope per Wisconsin law. The bullets are cast from wheel weights and I do not expect them to expand, but am unsure with the hollow point design. The chronograph measures the bullet speed at 1618 fps. This is charged with a reasonable amount of AA5744. I used MMP sabots. I also tried Oregon Trail Laser Cast .458 bullets at 350 grains with the same sabot and powder charge, nearly the same point of impact. In conclusion, I am very happy with this rifle and it seems to shoot everything with good accuracy.
