Ned, the answer is No ... The BC with a globe front and a vernier rear is still a No. The NRA deems the H&R not to be 'typical of the era', even though in my opinion it is the same platform as a Wurfflein. Further, it's a shame that the Committee won't allow this rifle. Many folks and juniors could be drawn to the BPCR sport and not have to spend big dollars for a high end BPCR. And can the BC be competative? Ya betcha it can. Mine shoots accurately to 1000yds with a globe front and a vernier rear
