Ok I have never heard of lapping scope rings before what is this just basically sanding them or something? Also I just bought a new Bushnell 5x15x50 MM Elite for my H&R .204 Ultra varmit. With a 50 mm bell will a standard high WARNE ring work or will I need to go extra high. I had to go with High for the .308 survivor so the hammer would clear. I wasn't worried about the bell on that one since it is a 3x9x40 (Elite).
